The Magician Under the Moonlight [Detective Conan]

Blurb:

Jiang, a great mage from another world.

He has spent years drifting from place to place, trying to find a way home.

Ten years later, he returns to his country and happens to witness Kaito Kid's dazzling performance beneath the moonlight. He decides to take him on as an apprentice.

One day, he rescues a blue-eyed cat who has been shot and is on the brink of death, making him his messenger. He also learns the truth about the Black Organization.

To help the blue-eyed cat, Jiang picks up another black-furred cat along the way.

Then the reappearance of Noah's Ark makes Jiang realize that the way home lies within it.

[Bonus Scene]

Jiang has recently been followed around by a blue-eyed cat. Wherever he goes, the cat goes too. Though Jiang could simply teleport away with magic, seeing those round, pitiful kitty eyes makes the softhearted great mage let him tag along.

Well, Jiang is a mature gentleman, after all. He can't just abandon a pet.

Hiromitsu Morofushi the cat grins slyly. "Yay!"

[Bonus Scene]

The black-furred, golden-haired cat is hard to get close to, and Jiang is troubled. To earn the cat's trust, he decides to use magic to turn him into a real cat. Then he can hold him in his arms, pet him, and get closer to him.

Rei Furuya, now a cat, is shocked, astonished, and embarrassed. In his anger, he ends up fighting the blue-eyed cat who was already there.

Damn it! If I can't beat this guy, surely I can beat a cat!

Hiromitsu Morofushi, who licked the cat's face to show his affection in a moment of excitement: "..." Damn it! Stupid cat instincts!

P.S. 1. Main character is the top. The love interest is either Hiromitsu Morofushi or Rei Furuya, not decided yet.

2. The good guys win, and the organization is destroyed.
