- All Your Powers Combined: Thanks to his initial ability, plunder, he becomes this in many timelines.
- By episode 5 (original timeline where the series starts), he got: thoughtography, telekinesis, and flight.
- In episode 9 (old timeline where all of ability wielders caught by scientist), he got: pulverization, telepathy, and permeation.
- By episode 12 (new timeline where Ayumi's has been saved), he got the ability as in episode 5, added with: time leap (though later it was disabled after one of his eyes damaged), collapse, invisibility, teleport, pyrokinesis, and channeling. Taken Up to Eleven since he's planning to plunders all of ability wielders around the world to stop the psychic phenomenon.

- Aside Glance: Does this often. It's even lampshaded by Nao at one point.
- Ax-Crazy: He becomes this as he falls into an intense sadness after his sister dies. He enjoys only eating and happily beating the crap out of local gang members with a sadistic laughter. Yuu does get better with the help of Nao. But yet again he falls into this as he vows to Plunder every ability in the world it ends up making him very violent and is prone to acting out in a rage. By the end of the series he's lost his memories but at least he's cured.
- Belligerent Sexual Tension: With Nao. At the beginning, they hate each other because Nao is the one who stops Yuu from abusing his power for his own gain. After working together at the student council, they slowly become friends of sorts. Yuu develops feelings for Nao after she helps him go back on his feet after his sister dies in one timeline and while she acknowledges they always argue, she's fine with the idea of being his girlfriend.
- Big Brother Instinct: He might be annoyed by Ayumi sometimes, but he also deeply cares for her, as seen in episode 5 & 6 when he treated a sick Ayumi. And much later in episode 6, after a revealing scene involving Ayumi collapsing part of her school building, Yuu immediately searched for Ayumi in the middle of rubble, ignoring one of the teachers and Nao's warning about impending debris collapse.
- Bishōnen: Exploits this as much as he can until he was caught by Nao at least.
- Blatant Lies: He rejects all of his suitors at his prestigious high school, saying that he's too busy studying. Not only does he not actually study, but he only has eyes for Yumi, and the real reason he's saying no is that he won't settle for anyone less.
- Break the Haughty: In the very first episode, his cheating gets exposed, he gets beaten up by Nao, he gets forcibly transferred to another school and the madonna of his school dumps him.
- Brilliant, but Lazy: Considering that he was able to pull a Rescue Romance that involved a near miss with a truck which involved pinpoint maneuvers with error meaning his intended rescue or him being severely injured or killed, he has to have some sort of smarts about him, he just chooses abusing his power over studying. Even while relying on his power to ace the exams, he's smart enough to realize that it isn't easy to identify who's an honors student (since students from several different schools take the exams), so he scouts out cram schools to find out who has the best chance of acing the test.
- Broken Ace: He's popular, charming, handsome, and a honor student. In reality, he's a selfish and manipulative Jerkass and a complete cheater.

- He dishes out a few of these in episode 7 after picking fights with various people.

- Cynicism Catalyst: Ayumi's death serves as a catalyst for turning Yuu's life upside down. He only gets better thanks to Nao.

- The Dreaded: He becomes this in episode 13, by all ability users around the world. Not only does he have many powers, he also is the only person with the ability to steal said powers.
- Drunk with Power: Zigzagged and discussed.
- Nao first approaches him to warn him about using his abilities for good instead of for selfish gains, lest he attract some unwanted attention from a certain organization that wants to use him as a lab rat. She later shows the aftermath of what happened to her brother who was in an insane asylum after having been experimented on. He reluctantly helps her student council to find other ability users to protect them, or at least get them to stop using their powers.
- He does start attempting to experiment with this in episode 7 against random thugs he picks fights with while suffering a Heroic BSoD and some Sanity Slippage. Fortunately he's saved before really going off the deep end by Nao, who was watching him the entire time. And in episode 10, it's further revealed that fortunately he was using his ability on ordinary people. Had he realized that he could steal other ability user's powers, he might have very well decided to abuse it and caught the attention of the scientists were it not for Nao.
- By Episode 13, the massive number of powers he had accumulated so far almost led to the worst possible outcome, with him contemplating world domination.
- Embarrassing Nickname: "The One-Eyed Grim Reaper," is this to him when he first hears it.
- Evil Costume Switch: Twice. In episode 7, he's wearing dark red hoodie jacket with maroon shirt as he slips some sanity after Ayumi's death. In episode 13, he's wearing black robe hoodie jacket with dark red shirt after his memories starts fading away and he's Drunk with Power.

- Also to Light Yagami from Death Note. Both have the same evil grin, same way of laughing and are somewhat similar in appearance.
- To Kanie Seiya from Amagi Brilliant Park. They're both similar in looks and personality, have the same voice actor, and have powers that give them glowing eyes.

- Eye Colour Change: His brown eyes turn yellowish-gold when he uses his ability.

- A God Am I: Yuu discusses this topic twice, once in episode 7, and again in episode 13. However, he doesn't do much beyond thinking about it, the first time due to Nao intervening before he start really Jumping Off the Slippery Slope. And in the second instance, her notes gives him a vague reminder of The Promise he made to her to return to Japan after stealing every ability user's powers and preventing their exploitation.

- Hikikomori: Temporarily becomes one for part of Episode 7 due to his sister's death.
- Irony: In episode 5, he comments about "Skyhigh Saito" being an embarrassing nickname, and in episode 7, he comments about giving a nickname to a thug he beats, as "One-Eyed Hoso-something". In episode 13, he becomes (in)famous around the world as "One-Eyed Grim Reaper", a nickname he himself finds out to be embarrassing.
- Jerk with a Heart of Gold: At the start of the series, he exploits his powers for his own personal gains, even going so far as to cause an accident and endanger Yumi's life to stage a Rescue Romance. Through Character Development, he's still not the friendliest person to be around, but gradually becomes more considerate of others and self-sacrificing.
- Laser-Guided Amnesia: It turns out that his memories were erased by someone named Maedomari. It only resurfaced through Sala's singing voice in Episode 9.
- Laser-Guided Karma: Yuu attempts to stab one of the thug's right eye with wooden skewer as part of his intimidation to him in episode 7. In the new timeline in episode 11, his exact right eye got slashed by another ability wielder. What's more, in Episode 7, he mockingly suggests that the thug can get a nickname that's a reference to him having one eye. His exploits end up earning him the nickname "One-Eyed Grim Reaper."

- Oh, Crap!:

- In Episode 6, when Kumagami finds an ability user inside the condo, the student council realizes that if none of the parents living in the condo can be ability users, it can only be a student who's at home sick. Yuu puts two and two together, then realizes Ayumi might have an ability.
- He also panics after losing an eye, and thus the ability to go back in time in Episode 11, resulting in his Collapse power destroying the building and killing Kumagami.
- Once Done, Never Forgotten: Nao enjoys giving Yuu grief for cheating on tests, especially when Yuu sympathizes for her circumstances, even months after the last time he cheated.
- One-Man Army: Forced on him in episode 11 when a group of people target him.

- Ripple Effect-Proof Memory: He somehow manages to recover his memories from the original timeline. How he did this without his brother's time leap ability is never explained beyond the implication that Sala Shane's music has peculiar properties.
- Samaritan Relationship Starter: He at first just thinks of Nao as a bossy, annoying girl. After he finds out she spent weeks watching over him after his sister died and she helps him get back on his feet, he starts to see her in a new light and develops feelings for her.
- Sanity Slippage: His progress in his worldwide journey to strip off all ability wielders of their powers subjected him to greatly increasing levels of mental stress, to the point that he started causing unnecessary destruction, almost killed civilians, and even contemplated godhood.
- She Is Not My Girlfriend: He repeatedly denies being interested in Nao when Ayumi starts teasing him about the possibility of Nao being his girlfriend.
- Story-Breaker Power: Once the true nature of his possession is revealed, it becomes the most broken superpower in the series. Yuu doesn't simply possess bodies, he can steal the powers of other people and use them for himself. With this, he can take his older brother's time travel power to save Ayumi by stealing her collapse power before it kills her.

- Took a Level in Kindness: He starts out as a self-absorbed and manipulative Jerkass, but he slowly begins to show concern for others and becomes a more decent person.

Lampshaded by Sala, who is comments that he was a nice person but is still able to tell that he wasn't always like that, despite having just met him.
- Trademark Favorite Food: Though he claims to absolutely hate it, Yuu likes Ayumi's rice omelettes, and will often eat it all while complaining about the odd sweet taste due to her pizza sauce. Nao uses this to help bring him back after he runs away and starts risking his life by picking fights with strangers.
- Victory-Guided Amnesia: Sure, he's able to plunders every ability wielder around the earth, with the very high price: his memory about everyone around him.
- Walking the Earth: What he decides to do in the final episode.

- Big Eater: Eats a lot. Even the sandwiches which weren't eaten by Yuu did not escape her.
- Big Sister Instinct: Towards Ayumi, also towards Iori Sekiguchi in OVA/special episode.
- Boring, but Practical: Her ability to hide her presence from a single person doesn't seem all that useful at first glance, but it's perfect for when she needs to observe/stalk a specific person. She ends up getting a lot of use out of her ability when it comes to tracking down individuals with superpowers or following Yu around during his Heroic BSoD.
- Broken Bird: She promised herself to never trust anyone again after finding out her "friends" were children of the scientists experimenting on her brother.
- Bully Magnet: She's bullied and beaten by her classmates on regular basis.
- Camera Fiend: She carries her video camera with her at all times. When a man punches her, she's more concerned about the fact that her camera might have been damaged. This later turns out to be because she wants to keep the camera to film a music video for ZHIEND, her brother's favorite band.
- Cruel to Be Kind: Her general modus operandi. She's willing to go so far as to use blackmail to get people to stop using their powers, but does so to prevent them from being experimented on.

She even takes him to see her brother, who was a victim in said experiments.

- Girlish Pigtails: She ties some of her hair in twintails.
- Good Is Not Nice: Nao's method of forcing Yuu to learn the errors of his ways for abusing his ability in the first episode is to beat him up and blackmail him into a HeelFace Turn.

- Guile Heroine: In order to achieve her goals, she often cunningly manipulates others.

- I Will Wait for You: Part of The Promise with Yuu. She also partially lampshades this trope during said promise.Nao: "I'll say it. 'I'll be waiting.'"
- Jerk with a Heart of Gold: She's bossy, self-righteous, indifferent and rude, but she's still a good person deep down.
- Jerkass Has a Point: Saying that Misa is already dead and that it's unnatural for her to still be channeled through her sister's body is a harsh thing to say to Misa's friends, but it's true. Shou gets upset, but Kouta gets him to calm down, and he reluctantly accepts the point. Misa herself knows this, which is why after saying goodbye to her parents and leaving a letter behind to her sister, she allows Yuu to plunder her ability, ending her existence.
- Kick Chick: Whenever she needs to beat someone up, she often incorporates kicks into them. She literally kicks the sense out of Yuu when he was going downhill after Ayumi's death.

- Magic Skirt: Her modesty stays safe despite all the kicking.
- Major Injury Underreaction: Nao seems to brush off the somewhat brutal beatdown she gets from some girls in episode 5. When Yu approaches her, she seems more interested in the fact that they have another student to find.

- Neat Freak: When she was over at Yuus apartment she caught his kitchen sink with a few dirty dishes, gets angry and insists on washing it when he shrugs off that there was no rush in cleaning only a few dishes.

Though this aspect of hers is very well-hidden.
- Nice Hat: Wears a baseball cap in episode 4.
- Not So Different: She tells Yu about her older brother who had an ability which then caused him to get experimented on to the point that it broke him. He then imagines that he and Ayumi would be in a very similar position had he of been caught by said scientists before Nao showed up.
- OOC Is Serious Business: In the special episode, Yuu is alarmed at how the normally dispassionate Nao rages at Honoka for distancing herself from her supposed best friend Iori just so she won't suffer any emotional turmoil from Iori's impending illness, insisting that Honoka be there to comfort her while she still has the opportunity.
- Parental Abandonment: She doesn't mention having a father, as her mother raised her and her brother. And she doesn't seem to trust her mother either anymore after being sold out to a group of scientists who then experimented on her brother to the point that his mind broke.
- Pragmatic Heroine: She usually either blackmails or intimidates gifted children into either stopping the use of their powers for self gain or enrolling in Hoshinoumi Academy. However, she does it so they won't be captured and end up like her brother.
- Rei Ayanami Expy: Just a little. She can be apathetic at times, often speaks in a monotone voice, and to top it off she has unnatural hair and eye color. However, she does have good intentions deep down and often hides it beneath a cold facade.
- She Cleans Up Nicely: Yuu blushes the first time he sees her in casual girly clothes.
- Single Woman Seeks Good Man: Downplayed. She makes Yuu promise to her that as long as he keeps his promise to steal every power and successfully gets rid of all of it, only then she will date him.
- Stealth Insult: After Ayumi suggests that she and Yuu would be a great couple, Nao says that someone with his intelligence and looks would be out of her league. It sounds like she's modestly saying that Yuu's too good for her, but in reality, she thinks of Yuu as an idiot.
- Student Council President: Despite being a first year student in high school. Joujirou later tells Yu that the student council isn't elected; rather, they're picked largely on who will use their ability the most, explaining why Nao is president despite being largely disliked. And considering Nao doesn't want anyone else with powers to suffer the same fate as her brother, she works hard to find said people and either get them to stop using their powers to prevent them from being captured and experimented on, or transfer them to her school to better protect them.
- Through His Stomach: In Episode 7, she tries to make Yuu feel better by cooking for him one of the Ayumi's sweet rice omelettes. She succeeds.
- Town Girls: The Neither to Yusa's Femme and Misa's Butch.

- Tsurime Eyes: Has sharp eyes.

- In episode 13, she stays by Yuu's side at the hospital after he's completed his mission and his promise to her. Sadly, he lost all of his memories about her.

A member of the student council.

- Iron Butt-Monkey: He does wear some protection under his uniform to minimize the damage sustained when he's using his Super Speed power. But that said, he causes a lot of destruction every time he lands somewhere, and often has Amusing Injuries, such as bleeding profusely from his head in episode 2 due to crashing into some large glass windows in the cafeteria.
- Large Ham: He is usually composed most of the time but when he is triggered by the situation (particularly anything regarding Yusa), he tends to go over-the-top.
- Mundane Utility: He uses his ability to buy some sandwiches without having to wait in line in the cafeteria. Unfortunately, with this method the sandwiches he grabs are random due to not having time to pick, and the resultant shock wave of his passage overturns every table in the vicinity. On top of that, Yuu mentions all the sandwiches are squashed as well.
- Muscles Are Meaningful: According to himself, the protector does not do enough to protect his body from the side effect of his power, so he must be strong enough to withstand, or at least minimalize the damage.

- Phrase Catcher: Always from Nao in regards to his fanboying of Yusa.Nao: "Such a turn off!"

First appeared in episode 9. Friend of Medoki and Maedomari. One of the founding members of "The Syndicate".
- Curtains Match the Window: He has yellow hair and yellow eyes.
- Heroic Sacrifice: In the original timeline, he saves Yuu by letting him take his ability before being shot by the guards. His fate is not yet revealed to the audience, though. He is however alive in the current timeline.
- Intangibility: His ability, "permeation", which makes him able to phase through walls, but as a drawback, it drains the stamina of the wielder.
- Jerkass: Attempts to blame Yuu for Kumagami's death. He ends up getting called out by the others on his Self-Serving Memory however.
- Never My Fault: He's the one who decides to rely on Yuu's ability to reset the past in case things go wrong, then puts all the blame on Yuu when Kumagami gets killed.
- Sitcom Arch-Nemesis: Has this trait towards Yuu, who he refers to as a siscon (sister complex) for spending all his time only with Ayumi.
- The Smart Guy: To Shunsuke's Big Good.
- Unwitting Instigator of Doom: As stated by Medoki, his over-reliant opinion to Yuu's time leap ability without knowing the limit/weakness of it indirectly causes Kumagami's death.
- You Should Have Died Instead: Implied with Yuu compared to Kumagami. After finding Yuu alive in the rubble, Shichino says that he'll be angry if Yuu survives but Nao and/or Kumagami die. When Kumagami ends up dying as a result of the building collapse, Shichino says it wouldn't have happened if Yuu hadn't been "trying to save (his) own ass."
