Maybe in another universe ~ Sanemi × Nezuko

Whenever someone asked Nezuko what was her type, she gave the same childish answer:
"It could be great if I could meet a man like hisha"
-Hisha is a piece in shogi. It's able to move both, horizontally and vertically. Becomes Ryuo once entering into enemy territory-
She finally met that man, his name is Sanemi Shinazugawa but, when she was a demon, Sanemi hated her for that but... now that she was a human... He is now 12 years old and he is 21 , his age when he became a demon, also because of his hunter mark, he was going to die, all she could think was: "Maybe in another universe we can be together."
-This is the history of the other universe-
