Nagara
The main character of the show. A third-year high school student who is bored with the world around him and feels resigned to life. He is distant from most of the other students.
- Dimensional Traveler: It's quickly revealed he has the ability to travel between different worlds (and take others with him). Unfortunately, it doesn't allow him to go back to our world.
- The Power of Creation: It's likely that his power is to create new worlds, not just travel between them.
- The Stoic: He often maintains a calm and expressionless demeanor.
- Tranquil Fury: He says very little, and when he does, he never changes his voice tone. The few times he gets angry, he says biting things without ever raising his voice.
Nozomi
A transfer student recently returned from Berlin.
Her power, "Compass", allows her to see a light in the distance, which apparently points the way to some mysterious goal—perhaps the way home.
- Back from the Dead: She is shown to have died in the original world in Episode 6. The drifting Nozomi then dies in Episode 10, turning into a compass, but the original Nozomi is alive in their world in Episode 12.
- Blithe Spirit: She's a creative, out-of-the-box thinker who is one of the few people to defy the student council's will. It's also mentioned that she lived abroad and isn't "familiar" with the rules and customs of her school.
- Establishing Character Moment: She tears apart a textbook.
- The Heart: In accordance with her power, is always the light guiding the others and motivating them to continue.
- Manic Pixie Dream Girl: Downplayed. She isn't explicitly a love interest, but she does initiate her friendship with Nagara, and her Blithe Spirit nature has a subtle but not insignificant impact on his reserved personality.
Mizuho
A rather abrasive girl who tends to keep her distance from people. She is taking care of several cats that once belonged to her grandmother.
Her power, called "Nyamazon", makes her cats bring her whatever she wants.
- Aloof Dark-Haired Girl: Taller than both Nozomi and Nagara, and generally keeps to herself.
- The Power of Creation: A variant. She can't create anything on her own, but she can have her cats bring her anything she wants from... somewhere, packed up in boxes. Up to and including a castle somehow.
- Power Misidentification: Her power is actually the thing that creates the permanent stasis in "This World". The "Nyamazon" power actually belongs to her cats, who aren't capable of creating things, but actually to copy things that exist from the real world.
Asakaze
An aloof, rebellious, and sarcastic student.
His ability, "Slow Light", allows him to control gravity.
- Gravity Master: His power lets him control gravity. He sometimes uses it to fly through the air. However, he can also do much more spectacular feats, up to and including somehow folding the entire school on itself, as if he was warping space-time itself.
- I Just Want to Be Special: Tsubasa argues he is obsessed with the idea of a task only he is capable of doing, which is why Ms. Aki could easily manipulate him.
Rajdhani
He is the main "intellectual" of the group, trying to discover the rules governing the new worlds, and a way to get back. Judging from his skin tone and name, he is likely at least part Indian.
His power, called "Pocket Computer", allows him to project a computer program onto the real world.
- Only Sane Man: He's one of the few people who focuses on systematically researching the nature of "This Worlds", and stays out of any conflict in the group.
- The Power of Creation: His power allows him to project a computer program onto the real world, which effectively means he can create colorful "toys" of any kind, from simple cubes through Mario powerups to autonomous robots.
- Techno Wizard: He's apparently a skilled programmer; the nature of his power implies as much. He's also able to rapidly create a digital currency app.
- Was Once a Man: According to Asakaze, he is no longer a human, and was turned into a forest. Mizuho smiles upon learning it, knowing that he is a Nature Lover and that is a good death for him in that world.
Hoshi
One of the members of the Student Council. A calm, highly intelligent and somewhat manipulative boy. He has a distinct star birthmark on his cheek.
His power is called "Heart" and it apparently allows him to manifest highly realistic images.
- Gratuitous English: The name of his ability in the original Japanese version is written in English.
- Meaningful Name: means ‘star’ in Japanese. He has a star birthmark.
Pony
The leader of the Student Council. She is not very talkative and tends to be strictly businesslike.
Her power, "Switch", allows her to exchange the positions of any two objects.
- Aloof Dark-Haired Girl: Similarly to her Foil Mizuho, she is a relatively tall girl with long black hair and a stern personality.
- Swap Teleportation: How her power "Switch" works. She can use it, among other things, to escape from a trap by switching places with random junk.
Cap
One of the members of the Student Council, and a former member of the same baseball team as Nagara. He seems rather naive. His actual name is Tanigawa.
His power, "All-Purpose Clubhouse", allows him to create various objects by concentrating in a room with no one else.
- Batter Up!: He plays baseball for his school and ends up using a bat to enforce his will.
- Drunk with Power: His brief stint as the leader has him become way too fixated on enforcing the rules, to the point where he tries bashing Asakaze's brains out with his bat (thankfully, due to the rules of the world, Asakaze survives without a scratch.) Once he is deposed, he turns out to be a fairly kind person.
- Only Known by Their Nickname: He is pretty much called "Cap" all the time.
- The Power of Creation: His power apparently allows him to create objects. This might be how he created the baseball diamond in Episode 4.
- Puppet King: He's initially voted as the leader of the group and is supported by the other council members to enforce the rules. It's all been a ploy just to test the powers of the other world and the Cap is treated as a pawn by Hoshi.
Hayato
A nerdy student who is one of Nagara's few friends. He is in charge of keeping a catalogue of everyone's powers.
His ability, called "ET", allows him to emit light from his finger.
- What Kind of Lame Power Is Heart, Anyway?: His power is rather underwhelming, compared to the others — which hasn't stopped him from ranking it "A" in his catalogue anyway.
Shanghai
A foreign transfer student from China, and Ace's girlfriend.
Her power, called "Electric Shock", allows her to control electromagnetism.
- Does Not Speak Common: She only speaks in Shanghainese (a dialect of Wu Chinese). Averted in the English dub, where she speaks the same language as everyone else.
- Shock and Awe: She has the ability to control electromagnetic fields. Her hair becomes charged with static electricity when she uses her power, sticking out to all sides.
Ace
A baseball prodigy, aloof and proud.
His power, called "Sweetwater", allows him to make any water drinkable.
Tsubasa Kossetsu
A tall, soft spoken girl with a broken arm.
Her power is to make metal objects stick to her. Her actual power is to read minds, but she lied in order to keep from being ostracized by the others.
- A Day in the Limelight: Episode 10. It explores her power and her feelings for Asakase.
- All Love Is Unrequited: Has feelings for Asakase, who likes Nozomi. Bonus points since due to her mind-reading powers, she gets to hear every thought he has about her.
- Blessed with Suck: Tsubasa has the ability to read minds, but it comes with a lot of baggage. She's not able to turn the ability off, so she's always aware of her classmates' two-faced natures. Tsubasa naturally keeps this to herself because she knows that if her classmates knew about it, it would make her life more difficult.
- Broken Pedestal: Implied. After Asakaze fails to save Nozomi, she appears horrified at his actions and thinks to herself that she never really understood him.
- Devoted to You: Tsubasa's infatuation with Asakase crosses into obsessive territory. She's an Extreme Doormat towards him, doing whatever he requests knowing that he both doesn't return her feelings and thinks very little of her. Asakase for his part is aware that she is attracted to him and strings her along just the same. Tsubasa, despite knowing his true nature, is convinced that Asakase is Troubled, but Cute and that he'll eventually fall for her once he realizes that Nozomi won't return his affections.
- Shrinking Violet: Speaks very quietly and keeps to herself.
- Smitten Teenage Girl: Tsubasa is head over hills for Asakase, the resident class delinquent.
Yamabiko
A large, talking dog encountered by Mizuho. He's actually a student from the same high school as the rest of the class. He took the form of a dog while trying to help a classmate and hasn't changed back since.
- A Day in the Limelight: Episode 8 explores his past including his and his class's entry into the other world, a girl he admired, and his transformation into a dog.
- Dark Is Not Evil: He's a large, dark haired, and overall fierce dog and could almost be mistaken for a wolf. Regardless, he's been friendly and helpful to Nagara's group and his doglike mannerisms that do come up are played for cuteness like Mizuho giving him belly rubs and feeding him treats.
- Really 700 Years Old: Despite being sent into the other worlds later than Nagara's class, he's been trapped in there for much longer. According to him, he's been there for 5000 years. This plot point reveals to the rest of the cast how differently the flow of time works compared to their own world.
