When the Undertale fandom meets the Gravity Falls fandom.
Undertale - Katana AU
Hahaha, I love this for obvious reasons! :D I'm proud to say I took this oath way back when I was 6 years old and laid my eyes on an anime for the first time! My very first anime was Shaman King and I'm mighty proud of that! Very close second was Inuyasha, sad that it ended but glad it well. (Now I just want the adventures of Shippo and I will be happy) What's was your first anime? :D
