Manga by author Amase Shiori

From Megchan's Scanlations: Gion Kenji is short and perpetually pissed off about it. Iwashimizu Sumiaki is tall but timid. Although it's bullies that bring this unlikely pair together on the first day of high school, it's the rugby club that will make them friends.

"Ethics" is the path of humanity, a principle that becomes the norm of morality. It is not necessary to learn it, but the lessons are laden with the truths of life. Cool ethics teacher Takayanagi confronts his students' problems and their beliefs.
