This is a complete aside: the title, along with the eyepatch on the girl, reminds me of the time that I learned that "bokukko" (girls that use "boku" for a first person pronoun, often conflated in pop culture with tomboys since "boku" is normally used by young boys and men) are considered kind of "cringe" by the Japanese because they associate it with chuunibyou.
In anime, in fact, while it might be normative for tomboyish characters to self reference with "boku", there are also "bokukko" that aren't tomboyish at all (IIRC, Danmachi's Hestia is one such case).
