Ok the new girl is definitely in my top 3 best girl of this manga just with 1 chapter particularly for how assertive she is! Finally not some "pl-please be gentle with me" from the mouth of a well build women (that doesn't mean I hate Helga, she is also in my top 3... But I always had a thing for onee san and assertive women like her) or tsundere whining like Leo (and I also love her)
