(Multiple heroines, but no wanton harem collecting, and not much romance. An invincible protagonist who kills anyone he can't stand. The story spans multiple worlds. P.S. The original couples stay together.)
From the start, he survived the Second Shinobi World War with the uncanny speed of Hiten Mitsurugi-ryu, Lightning Release Body Flicker, and a unique visual genjutsu, making a name for himself. Later, Hanzo bestowed on him the title Blue Fang. The protagonist's response? “Hanzo, you're the one who's full of it! Bluetooth is blue!”
Starting with Hiten Mitsurugi-ryu, he will dominate the ninja world (and eat, drink, visit brothels, and gamble his way through it).
Moves currently planned:
Heavenly Soaring Dragon Flash!
Flying Immortal Beyond the Heavens!
Two Green Snakes in the Sleeves!
One Sword Opens the Heavenly Gate!
When Otsutsuki Kaguya broke free of her seal, she saw a sword aura stretching from heaven to earth, splitting space apart. At the same time, a voice rang out: “I hear women are like fine wine, growing richer with age.”
Kaguya: Can I still make it back to the moon?
