Yokohama's famous gravity user, after meeting a certain bandage maniac when he was fifteen years old, his simple life changed directly into purgatory mode.
Looking around, there are children with problems all around; if you want peace and quiet, you will be surrounded by the best and the best.
Staying in Yokohama, my partner makes trouble every day;
On a business trip abroad, the partner is named Bai Lan;
He kindly saves people and recognizes his sister in the killing house;
Mysterious partner, unpredictable and difficult to deal with;
In this cold and ruthless world, fortunately, there is still a close friend, Shirou, who sticks to his conscience and retains the warmth of humanity, allowing him to drink and chat as a companion.
Jin Shining/Rin/Sakura/Illya/Alaya (in unison): "Dream!"
Chuuya: "Shirou, project the Lock of Heaven and fight with me to prepare me mentally."
Shirou: "Before that, Chuuya, you'd better look back and deal with the invitation to commit suicide from your former partner!"
PS: The main CPs in this article are Double Black Taizhong (guaranteed HE), and Jin Shijin (high probability of not being able to HE). There are (more than one) important female characters, and the attackers may accidentally enter.
