Loveless

After losing his older brother Seimei, Ritsuka Aoyagi faces a new school and memories he cannot entirely trust. A man named Soubi approaches him claiming to have been Seimei's partner, bringing news of a hidden world in which carefully chosen words become weapons.

Its combatants fight in pairs with distinct roles, and Ritsuka is drawn into Soubi's battles against people who know more about his brother than they reveal. The search for answers leads toward the organization called Seven Moons, where loyalty offers little assurance that anyone is telling the truth.
