Same animation style
Both of these have their first seasons with somewhat of a story and then having the second season not continue the story at all, just simply making up stories with its characters. (Might as well call them both a season of extras)
Has similiar animation and the girl with the pink hair looks the same.
Both crazy incest stories with moms and their step sons.
They are both a nicely improved animated version of their predecessors while not necessarily having a better story/laugh to them.
Kateikyoushi no Onee-san 2 The Animation: H no Hensachi Agechaimasu has adapted to using similiar animations as Stringendo(plus all the ones related to Stringendo).
