Isshin the 12th

""Haruka used Unbreakable to protect you!! That was surely because she thought you would protect even more people!! Therefore, I will take on her will and do the same!! Until the day Unbreakable passes on to her!! Now, what should build?! What should I protect?! I will protect any and everything!!""

Isshin the 12th is a blacksmith and a negator that was saved by Fuuko and Yusai. He's was the holder of Unbreakable in the 101st loop and Haruka Yamaoka's grandfather.

Appearance
He is a large, older man with wrinkles, mane of hair, a pointy beard, and bushy eyebrows. He wears the same armor his granddaughter, Haruka, would wear.

Personality
He is noble defender of his village, as well as a very dotting grandparent to a baby Haruka, so much that he eventually opts to not join the other Union personal when they prepare to time jump again so he can see Haruka grow up.

Spring Arc
He is mentioned in passing, his tombstone being shown and that Haruka has now become the next "Unbreakable" by her father.

Negator War Arc
He is first seen struggling against the same UMA that eventually killed Haruka's father. Just as he's about to be killed, Yusai manages to slay it and save him. Thankful, Isshin promises to repay them, but initially refuses to join the Union as he must protect his village in accordance to the village rules. He changes his mind and agrees to help after being told what his granddaughter did in the 100th loop, and vows to help until Unbreakable passes on to her. He then joins the effort in stopping the Bujora war in order to prevent Billy, Tella, and Creed's tragedies from unfolding, creating shields and blockades to defend everyone from gunfire, and later, aerial bombardment.

Unmove Arc
Following the recruitment of Shen, Feng, and Mui, he is drafted alongside nine others to infiltrate Chikara's school as its principal to prevent Chikara's tragedy. When UMA Colour appears, he and the other members leave the school to deal with it, with another person replacing him as principal and the school's memory of the Union being erased.

Sick Arc
As the rest of the Union prepare to time skip towards the next group of Negators, Isshin opts to stay behind so he can watch his granddaughter grow up. His fate is currently unknown.
