Will you be their teacher or a fellow student? A school life with returnees harboring deep scars.
About
One day, approximately 30 students from a second-year high school class were suddenly summoned to another world.
They gained powers as Heroes, Saints, Sword Saints, Sages, and Archmages, spending three years in that other world.
However, in the real world, only one month had passed.
The students who returned resumed their former school lives, but no one was the same as before.
Some lost loved ones in the other world. Some carry unrequited love. Some were betrayed by those they trusted. Some regret a past they couldn't protect. And some left behind the person they love in that other world.
Behind their smiles, they each hide their own wounds and secrets.
Characters
Haruto Takamiya
2nd year high school student. Black hair, blue eyes. Led his comrades as the Hero in the other world.
A reliable presence who is kind to everyone and has a strong sense of responsibility. Usually calm and polite, he is deeply trusted by those around him.
However, since returning, he sometimes gazes off into the distance. Behind his unchanging smile, he seems to be hiding something.
Mitsuki Hasegawa
2nd year high school student. Long reddish-brown hair, reddish-purple eyes. Supported her comrades as the Saint in the other world.
Bright, kind, and a popular person who is nice to everyone. She can't leave someone in trouble alone and always makes those around her smile.
She has been close to her childhood friend Makoto for a long time, but there is some distance between them since their return. If asked why, she just laughs it off.
Shion Tozaki
2nd year high school student. Long silver-purple hair, purple eyes. Wielded powerful magic as an Archmage in the other world.
Calm, intellectual, taciturn, and bad at expressing emotions. Prefers spending time alone rather than in a group.
Even after returning, she keeps her distance from others and is particularly wary of adults. There seems to be a reason why she doesn't trust people easily.

2nd year high school student. Light brown hair, green eyes, glasses. Supported his comrades with knowledge and magic as a Sage in the other world.
Quick-witted, calm, and attentive. Often serves as a confidant and is relied upon by those around him.
