But in the last year of their high school lives they are placed into different classes.

The answer deep, deep within their hearts is...

The path of youth and high school boys unable to voice their love.

From Aerandria Scans:

Hinako is the perfect high school girl. She’s beautiful. She’s graceful. She’s exquisite like a doll. She can be compared to a delicate flower. Oh, and she also beats up delinquents and perverts in her spare time. Does our delicate rose just like beating up people or is there a much deeper reason?

A spin-off from Houkago Play, this time it's about two girls who talk about their sex life, boyfriends or being a fujoshi.

Rengo Orii loves superheroes. Other people say that his favorite, Megalith, is an old man who should just retire already, but as far as he's concerned, anything Megalith does has to be true justice.

Rengo realizes that even though he might not look the part, he can still be the superhero he's always dreamed of being now, but it turns out copying Megalith's signature knee to the face isn't such a good idea when you're strong enough to kick someone's head off! Can a monster with a little kid's sense of justice really be a hero!?

From Evil Flowers:

Momoe is the type who accepts everyone’s opinions without contesting them regardless if they are right or not. That’s why people around her tend to call her dumb or stupid. Never showing a hurt face she’ll always smile back at them and she won’t even get angry. Takasugi, the school’s idol, gets to know her after some meetings in the infirmary and he’s amazed by her lack of self esteem combined with a warm smile ready to be given to anyone. She also starts to feel attracted to him, but is love what Takasugi feels or only curiosity?

This series is a set of several extremely short pieces: usually between 2-4 pages in length. They vary wildly in mood, character and art style, and the detail is often stunning.

Note: The manga was serialized in Kodansha's novel and manga fiction magazine, which does not targeted a specific demographic rather the general reader.
