In Japanese mythology, a "tsukumogami" is an object that gains a soul and becomes sentient.

Kazuya Kagami has kept his mother's obi close ever since her death, carrying it with him wherever he goes. One day, he barely escapes death when attacked by an amasogi in the form of a wig. Just as he thinks it's over, his cherished obi comes to his rescue, transforming into a beautiful girl named Kiriha, a tsugumomo that belonged to Kazuya's mother. With Kiriha's arrival, Kazuya discovers a new world filled with deities and tsukumogami, a realm he never knew existed.

Souichiro’s dream of ruling the martial arts scene at Toudou Academy comes to a halt when he clashes with seniors Masataka Takayanagi and Maya Natsume. These experienced fighters quickly put the brakes on the freshmen’s aggressive march through the school. Yet instead of discouraging them, the setback only fuels their determination to compete. Who are these incredible fighters at Toudou Academy? Is there anyone stronger than Masataka and Maya? And why is Maya’s younger sister so obsessed with Souichiro? The answers to these questions and more can be found in Tenjho Tenge.
