Master Ranpo and the Kite-Eyed Kitten

The boss had just come of age when, during a leisurely stroll after sneaking out, he transmigrated without warning, bringing along a black cat with pigeon-gray eyes. The boss, whose luck stat was only 'E': ... To find his way back, the boss and the black cat traveled through various worlds. They visited the detective agency in the main world, joined the Demon Slayer Corps to exterminate demons, raided a nine-tailed fox's den, and plucked scales from monsters. As time went by, the boss decided this black cat was obedient and handsome... and kind of cute, too. So the boss willingly became the cat's caretaker, blinding all the single people in the organization. * IF-route Boss Ranpo, a big shot in the command division of the Space-Time Administration. Best friend and partner: Fyodor D. Pairing: Dazai Osamu from the IF world -> Boss Ranpo. One-sided crush at first, then a couple. Ranpo is the top, Dazai is the bottom. P.S. Boss Ranpo is very strong, super overpowered, and definitely out of character. Theme: Companionship is the longest confession of love.
