Hi, I'm the translator. Renjaku says “mesu” in Japanese, which means female, but it’s a version of the word female that is usually used for animals. It's not a word that you would normally see used with people and is very degrading. Hence I thought “Bitch” would best convey that meaning.
I wasn't trying to change his character, or make him sound meaner. This is just a part of Renjaku’s character. It's how he is.
Also, it may not seem like it right now, but Renjaku is slowly changing. In the future chapters, you'll see that he's not all mean and angry.
Thank you!ヾ(❀╹◡╹)ﾉ~
Yes yes I know. I knew you were gonna reply with that as you did to others who talked about it. I was just joking, okay?
Guys he meant bitch as in a female dog, female dogs get heats too... I hope...
