Eishirou Sugata (守形 英四郎, Sugata Eishirō?) is a friend of Tomoki Sakurai and the president of The New World Discovery club, that the latter is roped into joining. 


Sugata is a tall young man who sports delicate white hair and blue-green eyes. He dresses in his school uniform, for those are his only clothes. He wears large, rectangular glasses. His facial expression is almost always neutral.


Sugata is the president of the New World Discovery Club (新大陸発見部 Shin Tairiku Hattukenbu). He is a scientist of sorts and is currently researching the Angeloids and Synapse with Nymph's help. He lives in a tent near a river and is always seen wearing his school uniform, as he has no other clothes, and continually praises various European explorers (such as Magellan and Columbus). He is highly eccentric and has some past involvement with Mikako's family; her servants even call him young master. He is also equal on combat abilities with Mikako Satsukitane. He and Daedalus frequently work together when he is visiting Synapse. Eishirou's intellect actually impresses the Sky Master himself.

He acts like a presenter of sorts at the beginning of most episodes in the anime, usually going on about the new world, and using various examples to explain his ideas, including historical figures. These presentations usually give small hints to what will be happening in the episode.


Sugata appears on top of the school building with a glider ready to jump, he checks the weather and makes the leap, it falls between the trees and wonders whether it was a miscalculation or weight, after that, he returns to the club room, shortly after, and Tomoki and Sohara appear asking for an explanation for the dream that was having Tomoki he replied that he had no interest in that kind of thing saying that " theories are based on reality," then it shows a map for Tomoki and Sohara, and ask what they think would be he replies that were electromagnetic waves on the planet, then he asks what would be one black point in traveling over the planet, they reply that they do not know, and he agrees, saying that's what they say, however, he reveals that this point is the "New World" after he falls into daydreams talking about the scientific community, after that he decides that the three will go to the cherry tree for more information about that black spot, but when the time comes, he is barred by Matsuyama Taizou, do not let him out of school because the flight with the glider, then after have gotten rid of the beard, he runs a bike asking him to get out of there quickly, but lose the signal because the black hole over the city.

Eishirou Sugata is first introduced in the Sora no Otoshimono manga and anime when Tomoki and Sohara arrive to school and find a massive crowd of panicking students who are looking up towards the top of the highest building on campus. Looking up, Tomoki and Sohara are horrified to see a man standing on the ledge, scanning the horizon as he prepares to launch his newest glider from the roof. Word spreads among the students that this man is none other than the quirky Eishiro Sugata, leader of the New World Discovery Club, and before the students know it, Eishiro grabs his glider and with a running leap, jumps from the roof into the skies. Carried by the stiff breeze blowing in from behind him, Eishiro and his glider maintain flight for a short while before crashing into a thick cluster of trees outside of the campus walls. While the students head off to their classes, the principal of Sorami High is seen rushing off in the direction of where the glider has crashed, in a huff over the latest in a series of dangerous stunts by the eccentric Eishiro. Sitting on a branch high up in one of the trees, the banged up Eishiro sees the test flight as a moderate success, ignoring the trickle of blood that is running down his face as the chimes for classes to start sound.

Back in his small club-room, Eishiro is disturbed from his research by the arrival of both Sohara Mitsuki and Tomoki Sakurai, who have come to inquire for his "professional" opinion in regards to the mysterious dream that Tomoki keeps having every time he falls asleep. Intrigued by this, Eishiro begins to theorize as to what these "dreams" could possibly mean, and it does not take him long to link them with his latest research project. He introduces the two of them to his studies in regards to a massive orb of disturbance that is currently orbiting around the Earth, and no matter what the most brilliant scientists in the world try, all attempts to discover the source of this disturbance have failed each and every time. Eishirou provides his own theory, stating that the orb, in fact, holds something that he has been dreaming of since he began his investigation into it: a new world. Stunned by his claims, both Tomoki and Sohara look on in disbelief as Eishiro links the dreams that Tomoki has been constantly having with this existence of a new world within the orb of disturbance. In a huff over just how crazy Eishiro is, Tomoki does not wish to be involved with anything that Eishiro might propose for him to take part in, but before he knows it, his friend Sohara is already telling Eishiro that they would both love to be involved with his efforts to see if it is linked to Tomoki's dreams. When he tells her that he will have nothing to do with it, Sohara threatens him with the prospect of having a brutal karate chop that she uses to pound him into submission, and this essentially forces Tomoki's hand so that he has no choice but to participate.

Since the orb of disturbance will be orbiting directly over the city of Sorami that evening, Eishiro arranges that the three of them should meet up at a special location just outside of Sorami so that they can witness it passing over them at midnight, but problems arise in this plan. Sohara is not allowed to go out past a certain time at night by her concerned parents, and Eishirou gets tangled up with the enraged Principal over the glider stunt that he pulled earlier in the day, resulting in Tomoki being the only one to be at the scheduled meeting place as the midnight hour draws near. Frustrated that no one will be showing up at the designated time, Tomoki plans to leave the meeting place, but is distracted when he receives a desperate call from the panicking Eishirou, who is racing over to the meeting place as fast as he can pedal his worn out bicycle. Eishriou begins to warn Tomoki of a sudden increase in disturbance from the orb, but is cut off by the loss of the signal when the orb moves directly over the slumbering city of Sorami. Looking up, Tomoki comes face to face with the colossal sphere hovering in the night skies, and before he can even try to think of what this giant orb of disturbance could be made of, a streak of white light emerges from the edge of the orb and rushes towards where he is sitting. Panicking, Tomoki gets up and runs for his life as the streaking light slams down into the ground where he had been sitting just moments ago, showing dirt and derbies high into the air as the impact knocks him off of his feet. Tomoki discovers that there is a unconscious girl laying down in the smoldering crater, but this is no ordinary girl, for she has a pair of large ping wings and seems to hardly be injured from the devastating impact. Not wanting to be caught up in this wild mess, Tomoki decides to leave the area, but when massive chunks of shattered marble pillars begin slamming down from the skies into the ground around him, he decides that he should save the poor girl from getting smashed. Back at the crater, he tries to save her, but when a speeding pillar comes racing down from the heavens and towards his location, Tomoki realizes that they are right in it's path and will be killed upon impact. He is stunned to find himself soaring through the air in a shower of pink feathers, and realizes that the girl he was trying to save has just rescued him from the impact of the pillar.

Eishirou finally arrives at the destroyed hillside that was to be the meeting place for watching the orb pass over, and is stunned to find a grimy Tomoki lying underneath a strange girl with wings emerging from her back. Freaking out, Tomoki gets out from underneath the mysterious girl that has introduced herself to him as the Pet-Class Angeloid Ikaros and has bonded to him to become his servant by the chain hanging from her collar. Interested by this development, Eishirou studies Ikaros with his eyes as Tomoki demands to know as to how he can remove the chain that is wrapped tightly around his right hand, knowing that he has school tomorrow and that people might find it odd that he is chained to a girl with wings. Prodding at the thick chains, Eishirou deems that it would take a long time to remove it, and asks Tomoki if he lives with his parents, to which Tomoki responds that he lives alone in his parent's old house in the aftermath of them leaving on a world tour six years ago. Eishirou tells him to go home and get some sleep, for they will try to puzzle out the meaning of these developments tomorrow at school since his theory regarding a new world has been confirmed with the arrival of Ikaros. Weary from the events of that day, Tomoki makes his way back home, the silent Ikaros following closely behind as he heads inside and goes to bed with the thought that perhaps this was all just a bad dream. The following day, Tomoki awakens to discover that the events of last night had actually happened when he finds Ikaros sitting next to his bed and realizes that the chain is still wrapped tightly around his right hand. Tomoki discovers that Ikaros has the ability to grant him whatever he desires through the use of her specialized Transport Card. Getting carried away by his perverted nature, Tomoki makes the first of many bad choices that eventually leads him to become the last human remaining on Earth, alone and isolated due to his perverted and dangerous wishes.

In the aftermath of Tomoki's wild rampage that is corrected by Ikaros after he wishes that none of what had happened that day was real and was just a dream, Tomoki wakes up and is somewhat surprised to find the curious Ikaros on top of him, looking at him with an unsure expression. Going downstairs after Sohara brutally delivers her karate chop on him after she entered his room and found Ikaros on top of him, Tomoki is stunned to find Eishirou Sugata sitting casually at his table, eating a bowl of soup for breakfast as he looks over one of the few old Transport Cards that Ikaros still possesses. Ikaros explains to them that these older model cards have the same powers as the advanced model she used to have, but once the older cards are used on a particular desire, it cannot summon anything from Synapse other than anything else other than the original desire. She also tells them that some older cards have unique abilities that can have unsuspecting side effects, no matter what they are used for. Realizing that they are going to be late for school, Eishirou and Sohara race off towards Sorami High, while Tomoki gets roughly halfway there before realizing that Ikaros is still chained to his right hand and is flying in the air behind him, attracting the attention of the people that Tomoki is running past. Racing back home, Tomoki realizes that they need to resolve the issue of the chain binding him to her, in which she tells him that she can turn the chain invisible. Allowing her to make that change, Tomoki once again races off towards Sorami High, but has to return back to his house once again when he realizes that Ikaros is still following him closely. Telling her that she has to stay at home while he is at school, Tomoki races off towards school, now quite late for his classes as the silent Ikaros sits on the mat in the center of the living room, bummed over not being allowed to follow her master.

After Tomoki accidentally "wishes" for Sohara to wear different panties other than the one with the dog icon that he accidentally sees when she falls over, which results in every pair of panties she tries to put on shooting off and flying away, Eishirou is forced to lend his club-room for her use as they try to figure out as to why this is happening. Tomoki, beaten and battered from the series of brutal chops that Sohara smashed him with after she discovered that he was the reason for her embarrassing plight, tells the concerned Eishirou that the Transport Card in his pocket had activated after he had seen her panties and thought that she would be better off with different ones, thus accidentally activating the card.

Sugata once had an older brother whom he looked up to. Sugata's older brother had a strong passion for flight and gliders, thus, Sugata developed similar interests. Sugata always followed his older brother around, and Sugata helped him with various projects. One day before a test flight, Sugata and his older brother had an argument over something trivial. Sugata was left to prepare the glider while his older brother was occupied by something else. Since Sugata was still heated from the argument earlier, he put minimal effort into preparing the glider, of which he would soon come to regret. While Sugata's older brother was in mid-flight, one of the wings broke off the glider due to Sugata's lack of sturdy preparation. Sugata's older brother plummeted to his death. With the responsibility of his older brother's death on his shoulders, Sugata was disowned by his family. Sugata's older brother was supposed to be the heir for head of the family, but with his death and Sugata's disowning, Sugata's younger brother is now the heir. Sugata set his sights on the new world as a personal way to atone for responsibility of his brother's death.

Powers & Abilities

While Eishirou does not possess any special powers or talents, he does specialize in using highly advanced technology and his meticulous methods of exploration in order to not only advance his research, but to come to grips with the technology from the mysterious world of Synapse. Being quite intellectual, he puts together theories and ideas based upon his research and findings, occasionally helping out Tomoki and friends whenever they come to a difficult understanding of certain situations. When Nymph introduces Eishirou to some of the advanced technology that she uses from Synapse, he takes a great interest in it and begins utilizing it to further his exploration and understanding of the mysterious world of Synapse. There is one downside to his genius, however, and it pertains to the fact that some of his methods or ideas usually result in negative side effects for himself or the hapless Tomoki, who falls victim to Eishirou's incorrect logic and intellectual abilities, Eishirou has shown to be quite a good fighter, managing to take down a bear when they went to camp.
