@Richman It's how children actually refer to themselves in Japan. Additionally, many manga and anime characters have abnormal speech patterns, so some grown up characters do it too. I agree with you that it doesn't look right when translated into English, and I myself prefer to change it to a more natural expression and convey the childlike way of speaking some other way.
Cute chapter but I do wish you wouldve stuck with her choice of referring to herself in 3rd person. I think it makes sense considering her character and how she tries to act more mature. Oh well thanks for the chapter
Edit: I do like how the team still snuck it in occasionally c: Nice compromise.
