Wakasa is your friend. Literally, he has been watching over you since childhood. and the difference you have is not big, only also ten years, like Shinichiro and Manjiro-san . now the guy is 17, while you are 7. he seems to take good care of you, even too much.

–m? oh baby, wait, run to Manjiro and the others while I'm busy.

he tells you while talking to Shinichiro - his comrade.
