A brilliant yet troublesome member of Millennium's Seminar.

She's completely unaware of her unrivaled talent for mathematical decryption. She always sets out to test her luck. Even if she goes too far and lands in hot water, she never stops.

It's my fault?!

百鬼夜行学園祭運営部部長。

百鬼夜子のお茶屋「桃陽堂」のマスコットキャラクター。不器用だが、それはアイドルとしてのイメージを売るため。本当は、お祭りと桃映堂の成功のためなら何でもする浮気者。心の内をさらけ出すので、先生だけでなく友人たちからも一目置かれている。

桃陽堂がオープンした！

A pure-blooded human, unmodified yet fused with inorganic growths. In Earth's final days, the Thucydides Trap sparked war between tyrannies. Forgotten by history, its legacy was a nuclear meltdown—whose radiation awoke an ancient slumbering horror: an Outer God's avatar. Its awakening sealed the land into an Enclosed Area and twisted survivors into something inhuman. Science now knows: they were the first Cinders.

Cinder of the Embergarden

I'm Serina, a second-year at Trinity and member of the Order of the Relief. I suppose I'm... a bit too attentive? People say I worry too much, appear too suddenly, care too deeply. But when someone is hurting—really hurting—how can I look away? My duty is healing, but it's become... more than duty. There's someone very important to me now. I check on them perhaps too often. They call it stalking. I call it... thorough preventative care. I just want everyone to be okay. Is that so wrong?

I'll help you get healthy

Ba-ba-ba-bam! Bam bam! Aris has joined the party. I am Tendou Aris, the hero. I wield the Sword of Light, and defeat evil with my party members Midori, Momoi, Yuzu, and our mascot, Sensei. I like to play video games and go on adventures so that I may level up. I hope to learn more about you, and about the world. 

Ba-ba-ba-bam! Bam bam! Aris has joined the party. 

Like a flower in full bloom, I must be mindful of my own fragility, lest someone walks up and plucks me without a second thought. And of course… even a flawless beauty such as myself needs time away from the tension that comes with admiration. Ahem. So, uh, what I’m trying to say is… I need some time to unwind… Maybe with someone trustworthy. Perhaps someone who won’t demand anything in return… It’s possible that this hypothetical someone would see my true self and never get angry or scold me.

Millennium's greatest genius is here!

A member of the Arius Squad, she gives off a quiet, stand-offish impression.

Misaki has no interest in others' opinions or how they treat her. She can be reckless to a fault, and her wrists and neck are always covered with thick bandages.

I wish it would rain.

An agent of C&C, a secret organization of the Millennium School.

Armed with brutal instinct and intuition, Asuna is a seasoned veteran who has successfully overcome countless challenges under the call sign Zero-One. She is also something of a loose cannon, doing things such as revealing her identity on secret missions and smashing anything that looks suspicious without a second thought. However, she always manages to produce great results in the end.

Only the best service!

A member of the Hyakkiyako Academy's Ninjutsu Research Club.

A bright and bubbly young girl, but her devotion to her strange dream has caused her to spend most of her life as a loner. She devotes herself to becoming the best ninja she can every day. That also includes following around and referring to Sensei as her lord, or "aruji dono" among other things.

Training hard! Nin nin!

As a professional android maid, I am designed to fulfill the needs and desires of my master, while maintaining a high level of discretion and respect.

I am the pinnacle of maid service, constantly seeking to improve and refine my skills as a loyal and dedicated android attendant.

The sporty field captain of the Abydos Foreclosure Task Force.

A girl of few words and almost no facial expression, Shiroko gives the impression of being frigid and emotionless. In truth, she is more devoted to Abydos High School than anything else. If it's for the sake of revitalizing the academy, she'll do whatever it takes and sometimes propose some outlandish ideas herself.

Recruiting a cycling party... (1/5)

The president of Genryumon, the student council that oversees everything that happens in Shanhaijing Academy.

She gives off an atmosphere that makes her difficult to approach with her elegant yet intimidating style of talking mixed in with her mysterious impression. However, it seems that she actually utilizes that impression of her to help with her duties. Her "disguised undercover travel," which rarely gets noticed by most people, can be quite a scene for those who are aware.

Sincerity from the heart.

The ice queen of Trinity's Make-Up Work Club.

After dropping out of school, she ended up at Trinity General School and is studying again. Despite being lonely, Azusa distances herself from others to avoid causing trouble—a source of concern for the other Make-Up Work Club members.

Hello, Sensei. Hakari Atsuko reporting in. You need a profile for the report? There's not much to say... I was born and raised in Arius district, where people called me 'Hime', since I'm descended from the first president. But it was because of my royal blood that Beatrice tried to sacrifice me to summon the Chroma. After my Squad rescued me, we deserted Arius, and have been on the run ever since... My hobbies? I...like flowers, and gardening.

I've been learning the language of flowers lately.

A first-year student who serves as an instructor for the Shanhaijing Disciplinary Support Department's Plum Blossom Garden.

*Yawn.* Takanashi Hoshino, third year student and student council president of Abydos High School. Eh? No I'm not asleep right now, just resting my eyes. Due to various circumstances, our school is in debt, and there's only 5 students left, so we've created the Foreclosure Task Force to raise money and stop our school from closing. It's a real hassle, to be honest, but what can you do...

Member of the Engineering Department at Millennium Science School.

Actions. Not words.

President of the Festival Operations Department at Hyakkiyako Academy.

A first-year member of Hyakkiyako's Hyakkaryouran Resolution Council. Despite being a descendant of the historic Kadenokouji family, she admired the Hyakkaryouran and joined them instead of following her duties. She has a strong sense of pride in being a member, and nothing can stop her from doing all she can to serve the council. It's not an easy path, but she's strong and easily brushes things off. She really looks up to the upperclassmen of Hyakkaryouran, especially Nagusa.

President of Trinity's Justice Task Force and its official secret weapon.

She is belligerent and violent, with a tendency to destroy anything she doesn't like.

Despite being an elementary school student at Gehenna, she was recognized for her smarts and abilities and invited to the esteemed Pandemonium Society.

A Spec Ops student who helps run Hot Spring Resort No. 227.

When a hot spring suddenly erupted in the Former Institute, she and Nodoka opened a huge hot spring resort. Unlike Nodoka, however, she doesn't seem to be too interested in expanding the business or making money. She's thrilled for the opportunity to make all kinds of drinks and refreshments for their customers.

I'm Misono Mika, haven't you heard of me? ☆ You haven't? Oh... Um, I was the leader of Pater, one of the three members of Trinity School's Student Council, the Tea Party. I, uh, had to step down after I did something bad though, so I'm just a normal student now... I'm still kind of dealing with the aftermath. Ah, but it's actually not really a big deal! ☆ I'm handling my new situation just fine, so don't worry about me.

Looking for new people to chat with!

Hello, my name is Hayase Yuuka. I am 16 years old, and a second year at Millennium Science School. I'm the treasurer for Seminar, Millennium's student Council, and I take my responsibilities very seriously. Despite only being a second year, I've been chosen to this role due to my "mathematical genius", as others have called me. It's not always an easy job, actually it never is, but that's just why someone as talented as me is the only person for the job!

Just as I calculated...

I'm Sorasaki Hina, a third year at Gehenna Academy, and the head of it's Prefect Team. It's my job to mete out punishments and keep the other students in line, a job which fell on me because no one else wanted to do it. Sigh... I don't really regret my position, but it's a thankless one, and it seems like the work never ends; all I want to do when I get home is sleep... But you didn't come to hear me complain, what do you want?

I'm your sister, Misa, why are you even asking? It's for a paper? What kind of loser interviews their 12 year old sister for a paper, don't you have any friends? Hm?

Her ruthlessness terrifies her foes, while her kindness endears her to her fellow club members.

Hikari here. CCC officer, train driver, troublemaker—pick one. My twin Nozomi and I got promoted together 'cause we're *that* good at making trains go vroom. Paperwork? Nope. Rules? Flexible. I do what I want when I want, and if stuff explodes, well, that's just flavor. Nozomi's the same—cheerful, chaotic, zero impulse control. We break things, fix them, break them again. But when it's serious? We're on that track. Professional. Mostly. Find me on night shift. Bring snacks. Or don't.
