SaneGiyuu time travel

After the war Sanemi and Giyuu started getting along more. Giyuu cut his hair and left out all his pain and regrets and became a more expressive person. While Sanemi started trying to be kinder but couldn't help but drink to forget the pain, becoming a heavy alcoholic, thank god he restrained at the thought of being like his father and the fear of harming Giyuu, who was living with him after destroying his estate by accident.

After the war a lot of animals(mainly cats, or animals with fur) from the city they spawned in during the sunrise countdown were injured, so Giyuu took care of them, and some people adopted them.

Sanemi became a hunter, with the old habits, he helps Giyuu take care of the animals, as much as most dislike him, but he helps people by selling the meats and fur(not Giyuu's babies, Giyuu would kill him if he did that)

So, SaneGiyuu was having a "good life", their finally 23, they were taking care of an injured kitty when boom, they got teleported to in front of Oyakata-sama, from 2 years ago.
