iin chiyo so she's an iincho
okay fine, i guess when you make too many character, you also being kind of lazy about naming huh, its just how it is i guess
welp rentarou already got a set of oyakodon in his harem, so if you add cousin in the mix its still fine maybe. as for her ages, it matters not because its not like they have way too much age gap, so when rentaro reach 20, its basically already legal anyway
also the uncle shirt, while you can read it is as CHO AI (super love), you may also read it as CHIYO AI (love chiyo), so well...a cultured(?) dad we got here
