Willow branches provide shade, that's it!

Kanae Kocho: "I invited him to a tea party ninety-seven times, and he refused ninety-seven times. He's so gentle."

Shinobu Kocho: "Why should I be trained by iron fists? It's infuriating, sister!"

Unofficial synopsis: Yagyu In transmigrates to the world of Demon Slayer, but the system believes he is in the world of One Piece and identifies him as a Marine.

You can earn Navy Points and rewards by doing things that are in line with the Navy's rules.

Yagyu In: No, buddy, is this right? Where did this pirate from the Demon Slayer world come from that I need to catch?!

Pirates are attacking! Strike immediately to capture or kill them!

Looking at the man-eating ghost before him, Liu Shengyin realized that the system had gone mad.

From then on, the Demon Slayer Corps had one more instructor who liked to smash people's heads with his iron fist of love.

But the temperature in the room seemed to rise higher and higher; a flash of lightning seemed to be seen between their eyes. The blonde girl with pigtails gritted her teeth, while the long-haired girl stomped her feet. Finally, they started arguing. The short-haired girl looked at them, but they seemed to ignore her and continued arguing. She put down her phone. "Stop arguing, give me, Hui, some face." A 0.0000001-second pause. The clenching of fists and the stomping of feet only grew louder. The short-haired girl had no choice but to pick up her phone again.

He is the man who respects Kaido the most;

He is Kizaru's close friend, a rascal in the eyes of Sengoku, Garp, Zephyr, and Tsuru, and the Five Elders' number one enemy.

He was the childhood nightmare of Luffy and his brothers, the target Zoro vowed to kill, the scumbag pervert Sanji hated most, the pervert in Franky's eyes, and the idol of Usopp and Chopper.

He was the opponent who made Red-Haired Shanks lose face; the man who broke Hawkeye's defenses.

He is the one who tramples on the dreams of Doflamingo, Gecko Moria, and Kozuki Momonosuke.
