Hihi lovelies! Here's Extra Cup 1, a short chapter about Aku x Natsu's night on Xmas Eve !!
Timeline wise, this is right after Chapter 3 of CVB's main plot, and while it was never included in Volume 1, it should've been there as Chapter 3.5, hahaha.
Share your love, thoughts, and comments on Discord. I'm working on Chapter 9 already, thanks for your patience!
