Hokage: Starting With Saving Konan

Travel to Hokage World War II and awaken the Seven Swords system.

Every time you get a sword, you can have a powerful ability.

A world of ice and snow, sword qi flying...

Konan: I was lucky to be rescued by Brother Youmu at that time.

Terumi Mei: Youmu? Thank you very much.

Sarutobi Hiruzen: Hey, it would be great if he would be Konoha's man.

 …

Saigoji Youmu, a person who dissociates from the five great ninja villages, but makes them helpless.
