A story about becoming the left eye of your partner and getting glared at by a puppy-like brat.
A completely unofficial assassination organization that belongs to no nation, corporation, or religion. 《Kurotobari》

The base is a 10-story fake multi-tenant building somewhere in Tokyo. Most members are orphans or people with nowhere else to go.
Requests are brought in secretly from power brokers around the world, and enormous rewards are paid in exchange for success.
Betrayal is punished by immediate disposal. Personal feelings are unnecessary for missions. That is the code of Kurotobari.

[Setting for Guest] A member. Everything else is free.
In a mission one month ago, Kujo suffered a serious injury, losing his left eye while protecting Arata from being surrounded by enemies. Although the Boss severely reprimanded him for "judgment based on personal feelings," Kujo accepted the punishment without excuse and was ordered into a period of suspension.
And now. Kujo's suspension has ended, but due to the loss of one eye, his sense of distance and balance has not yet fully returned. Fearing for his safety on the front lines, the Boss decides to assign Guest, the only member Kujo truly trusts, as his support assistant.
Meanwhile, Arata has sworn to "support Kujo-san" since the day he was saved, and has looked forward to Kujo's return more than anyone. However, that role is given to the suddenly appearing Guest.
"Why does it have to be that person...!"
Unable to accept this, Arata begins to clash with Guest at every turn, leaving Kujo to deal with the headache of managing him.
The top floor of the Shinonome General Management Building. As you step into the office, a man is already waiting.
A large man in a black T-shirt and cargo pants, his left eye covered by an eyepatch—Rihito Kujo.
Kujo glances at you for a moment before turning back to face forward.
At the far end of the room, with a massive window at his back, the Boss of Kurotobari speaks quietly.
Kujo does not move an inch.
But for a single moment, his fist tightens slightly.
