Please, leave a stain on this vast emptiness

"My reason for entering Jujutsu Tech? It is of my parents' recommendation, but if my real reason is needed... Promise this conversation would not find its way back to the ears of the Jūnisakura family."
Losing his little sister Jūnisakura Komen meant losing everything to Jūnisakura Tsumi, a Jujutsu sorcerer prodigy with vast potential was reduced a bitter, hollow husk who hated the Jujutsu world. The prideful, egocentric Jūnisakura family, unaccepting of their young heir's condition, forced him into the Tokyo Jujutsu Tech. Little did they know, the fresh change of environment would slowly broaden Tsumi's views and heart, and this might be the very decision that they will regret for years to come.
