The Boss Dazai Has the Villain's Script in Hand

[An idea I don't know how to write] [Thoughts, outline, and setting in the story] As a boss Dazai, Miss Tsushima does a great job of not fitting in with all sorts of Dazai-type creatures. Unfortunately, Miss Tsushima has been handed the villain's script. One day, Miss Tsushima transmigrates to the main world... The Armed Detective Agency, Port Mafia, Special Division for Unusual Powers, Decay of the Angel, Hunting Dogs, and the Guild are all in danger. The first day the boss goes missing, one of the Five Executives, Mori Ogai: holding his hairline, diligently handling the organization's affairs in the boss's place.gif One month after the boss goes missing, Armed Detective Agency clerk Oda Sakunosuke: Tsushima will surely be doing well, right? Beside him, the Akutagawa-branded paper shredder: If anyone dares to offend the boss, I will never forgive them! Three months after the boss goes missing, Port Mafia boss's guard captain Gide: ... Gide, who transmigrated to the main world with her, trembles beneath his cloak. If he had arrived even a moment later, the alternate versions of the boss's friends and family he knows might have been wiped out by the boss herself. Chuya Nakahara, forced to trade blows with Miss Tsushima from another world and still getting suppressed: Witnessing a blue mackerel take flight, live. Miss Tsushima, holding the villain's script: Your world's book? Fine. In the next second, it's mine. Note: This is my take on Miss Tsushima! She really doesn't fit in with most Dazai-type creatures. There are secret identities, but no System. Everything depends on Miss Tsushima's acting skills √ The plot is divided into four volumes and crosses over with three worlds. Definitely heartwarming! (Absolutely certain.) Theme: A happy ending must be achieved.
