It's just a prank bro!!
To research for this piece I watched the im@s U149 anime. I felt like the series had characterized Arisu with some serious hall-monitor energy... so it was easy for me to imagine some of the other girls pranking her like this, to get back at her for being such a wet blanket (heh) all of the time.
I was originally only going to draw Haru to accompany Arisu, but after watching the anime, I came to like Risa a lot. She's so bratty and so much of a papa's girl! I thought she fit in as a good accomplice for Haru in this piece. I might need to draw her getting her comeuppance one of these days...
I know that I themed April around wetting, but... I couldn't help myself, I had to include messing alts. It's not breaking theme if it's added as an extra!
Anyway, I hope you all enjoy! I had fun working on this one, and challenged myself in a couple of areas. As always there are many things I want to improve, but many things that I am happy to have attempted as well. Look forward to the next poll!
