In Every World, Men Hit on Our Swordmasters

Kuroko Tetsuya's spiritual power attracted nearby yokai from the moment he was born. He nearly suffered a "divine abduction," but as a result, he met a true god.

A man who called himself a sword tsukumogami signed an outrageous contract with his parents: they would raise Kuroko for one month, and he would raise him for the next. Worried about their son's safety, Kuroko's parents reluctantly agreed.

From then on, Kuroko Tetsuya had two homes. One with ordinary parents, and another with a group of swords who called him their master.

Having a castle of his own at such a young age, Kuroko Tetsuya's power goes without saying.

The swords often take their young saniwa to visit different worlds, but as the young saniwa grows up, they realize that some things are becoming increasingly troublesome.

World One: High School Detective or Elementary School Grim Reaper

The swords' mission in this world is to find the source of the temporal chaos. Since the mission will take a long time, Kuroko Tetsuya is sent to study at a high school.

Their master studies hard while the swords earn money to support the family. It should have been a happy family, but then some shameless dark-skinned man started trying to seduce their young master.

World Two: Demon Slayer

A sickly nobleman killed a doctor to satisfy his own desires, turning himself into a monster that could not live in the light. The monsters he went on to create killed family after family.

The swords sympathize with what these people have gone through, but that doesn't mean they can play the victim and trick their master!

[Young Master Akashi, Orphaned by the Demons x Head of a Shinto Family]

World Three: The Red Scarf Falling from the Sky

A fragile world, painstakingly kept together by one person...

[Other worlds to be decided]

A few notes:

1. The protagonist will probably first fall in love with counterparts from other worlds, then with the basketball boys of his own world. (One-to-one pairings in each arc, different endings.)

2. The title is undecided. I can't think of anything better for now.

Theme: Hold on to what you can.
