Yay it's back! As an avid fisherman myself I like it when chapters have more of that going on, and the stream trout and mahseer are much more my style than the bass he usually mentions
Honestly with how athletic the mom is and the big fight mentioned I bet the mom is basically an ex-hero and met the dad when she was sent to eliminate him
Nice chapter as always! On page 2 something that confused me is Piero-san is referred to as she, everyone looks like a woman (have we seen any actual women yet?) but aren't they still usually called he and such since they are male?
