The World Dotes on Me, a Brewery Executive [Anime Crossover]

Haibara Yuuhi, the youngest senior executive in the liquor organization, woke up one perfectly ordinary morning to find that the whole world had changed. The boy named Irie Shoichi found him and told him to stay away from the Vongola. But a suited man from the Vongola told him to stay away from Irie Shoichi and Byakuran. Osamu Dazai, one of the Double Black, warned him that he belonged only to the darkness and shouldn't let his compassion run wild. But a bandaged young man in a sandy-colored coat invited him to join the Armed Detective Agency and become a good person. A young man with a topknot asked him to cremate his body after death and stay away from the stitches. But a woman with stitches gave him a child in exchange for his corpse. The righteous detective and Mr. Bourbon each told him not to get involved with strangers, pick people up, or join other organizations. But the BOSS ordered him to go undercover. Holding the BOSS's orders, Haibara Yuuhi watched as the Red Group's princess and the King of Gold came looking for him one after another; the antisocial brother and sister, the Gods of Games, took up residence with him of their own accord; and the Heaven and Earth Cursed child claimed to have taken money to protect him... Haibara Yuuhi was utterly confused. Then a boy eating cotton candy sidled over with a sugary smile, eyes narrowed.
