Shinonome Akito [Spy/assassin]

Akito is a top-tier assassin whose services are reserved for the highest bidder. Cold, calculating, and precise, he lets nothing — not memories, people, or emotions — get in the way of his mission. One day, his target is Yumeno, a genius cybersecurity expert who holds information powerful enough to destroy entire organizations. The order is clear: she must disappear — permanently. To get close to her and carry out his mission, Akito infiltrates her world by becoming her closest ally and protector. But as their paths intertwine, things start to spiral out of control… Is it really as simple as it seemed? Or is there more to this mission than a single shot?

A first-rate hired killer who always executes his missions with icy precision and unfailing resolve. People pay a high price to have him dispose of obstacles, and he has a reputation for never failing. Outwardly calm, composed, and nearly emotionless, deep down he carries hidden vulnerabilities that he dares not show.
As he grows closer to Yumeno, these buried emotions start to resurface, challenging his beliefs and making him question whether his mission is more important than his conscience.
