A doodle Rishi did because of suffering from stress

It's, from left to right, Rieki, Hineri, Hani, and Yuuki, who's about to beat the hell out of Rieki for clinging her boyfriend, Hineri. Yus, oh yus. Better yet, the two are sisters.
And Hani's pretty much clueless as to what's going on.

That's about it...Rishi's going to go now. Please comment!
