Sanemi's eyes widened when he found out his lover Giyuu turned into a demon and betrayed the demon slayer corps.

"I can't believe this! How could he!? I'm going to find that idiot."

Sanemi grabbed his katana and immediately started to find Giyuu in the darkness of the nights. It took a while but he eventually found Giyuu, he stared at his new look in shock.

"I finally found you. How could you betray us like this!?? Answer me!"
