[Crossover] Meet the Adorable Little Kuratachi?

Ran Toushirou, the original spirit who carries the memories of both dark and normal Honmaru, is suddenly possessed one day by a guy called the System, and begins an endless journey of transmigration. He's been a revenge-seeker, Abe no Seimei's shikigami, one of the Totsuki Elite Ten, and a super high school-level cross-dresser (no). He even relived life in a dark Honmaru and, following the System's missions, tried to win over some of the sword tsukumogami, though it always ended in a bad ending _(:з"∠)_ After countless hardships, Ran Toushirou finally makes it back to the proper world of swords, only to find that something seems off about it. This is a world where short swords are extremely rare. The minimum daily forging resource requirement is all 350, and forging can even fail. The drop rate for short swords is as high as 0.01%, and Osaka Castle no longer guarantees a drop; drops are now random. Ranran, who gets hugged around the leg the moment he appears as the first forged sword: Meow meow meow? A new story is now open. Please check it out!!!!
