I didn't get the chance to draw Yumeko after watching Kakegurui so I'm happy I could finally draw her^w^
Yeah, she's pretty mentally unstable in the anime and manga series. She has a totally out-of-control gambling addiction that more often than not scares the living shit out of almost everyone around her on a regular basis with how far she's willing to satisfy it. Basically, she's Atem/Yami Yugi from Yu-Gi-Oh, except that's she's female, hot and completely nuts.
The series is called Kakegurui if you ever want to check it out, it's pretty good. Btw, I hope I didn't come across as disrespectful, intrusive, obnoxious or rude in any of my comments towards you, and I sincerely apologize if I did. It definitely wasn't my intention.
Ikr? That would be a nice addition to the roster. In the meantime, I think it might still be on Netflix if you ever want to go that route (I watched it about a year ago on that platform and read the whole manga right before I watched the anime).
