This school belongs to the universe of the Inhabitant of infinite the.

This school appears in volume 8 when Anotsu comes in Kaga to take possession of it. In fact the schoolmaster, Kensoui Ibane, concluded an out-of-court settlement, to yield the school to him if it accepts his adopted girl, Hisoka, in marriage. The majority of the pupils are nevertheless against integration with the Itto-Ryu and will be opposed to Anotsu (and particularly Iriya which is in fact in love with Hisoka).

The turning of the school will be marked when the Bakufu orders with Kensoui to kill Anotsu after the marriage of this one and Hisoka. This last will escape from little a trap tended by the Master. Kensoui makes Seppuku then followed soon by Hisoka. The other members of Shingyoto-Ryu will then decide to kill Anotsu, Iriya in tète.

In spite of their efforts, all the disciples will be killed by Manji, Magatsu, Anotsu and Makie which will have been combined for the occasion.

The disciples of Shingyoto-Ryu involve themselves hard while following the old precepts of the fencing. They are all very good fencers, but between a combat in a dojo and a combat with death, there is a margin.
