Bungo Stray Dogs arc:
"Did you hear? They say the haunted house district has ghosts at night lately!"
"Huh? Do you mean that ghost story about the guy covered head to toe in bandages who's been showing up recently?"
"That's the one!"
Just then, a sixteen-year-old Dazai walking by overhears them.
"?"
Why are those guys looking at him so strangely? Ugh, gross!
Then, by chance, he meets someone who likes wrapping himself in bandages almost as much as he does. He's about to say hello when a scythe swings at him from the opposite direction. Just as he is about to reach the long-awaited slopes of Yomotsu Hirasaka, a mocking voice rings in his ears.
"What? That's it? Boring."
Jujutsu arc:
An obscure young man appears in the world of jujutsu. His origins are unknown, and he has no cursed energy, yet he is incredibly powerful. They say his sword is a special-grade cursed tool, and that he uses an unheard-of sword style. With a single strike, he exorcised a special-grade cursed spirit.
"Is that really true?" A man rubs his chin, his face full of disbelief. His companion tips back the last of his drink and is about to scoff at those people for exaggerating when he happens to catch sight of a figure. A pair of empty, blue-green eyes peer out through the haze. The stranger wears a haori and has a sword at his waist, the same one used to slay the cursed spirit. One look is enough to make the man feel as if he has fallen into hell. The figure soon looks away, leaving him frozen in place, scared out of his wits.
Detective Conan arc:
A mysterious young man is suddenly assigned to the Organization. Though physically frail, he has as much authority as Gin, and many people refuse to accept him. He looks so fragile, with a slender neck that seems as if it could snap with the slightest touch, yet he is a hundred times more ruthless than anyone his age. It isn't until would-be assassins are torn apart by an unknown black blade that they realize: those who seem the most defenseless are often the ones with the most astonishing means at their disposal when it matters most.
"Go to hell and repent."
The young man speaks softly, then covers his mouth with a hand and coughs muffledly.
The protagonist will appear under female secret identities. If that bothers you, don't read.
Theme: A place to stash my wild ideas.
