(Comprehensive) a Group of Knife Masters Around

As an old monster who has lived for thousands of years, Nian Nianjian himself, no, this sword, just wants to live an ordinary life, for example. . . Drinking tea, walking birds, raising flowers, and fighting dogs (foxes). However. . . Shuen Nian: ... I really don't want to do so many things. If possible, please let me be like Akashi. In fact, Duan Nian is a free-spirited person who becomes an adult again after N thousand years. . . Of course you have to indulge yourself. PS; Duan Nian was once a human being. Of course, as the protagonist, he must not be ordinary (grip his claws). PPS: It's mainly about the background of swords. Don't ask why the Chinese artifact can speak Japanese, because. . . He is a Japanese major (hahahahaha) All members single arrow → male protagonist +
