@CrazyPotato the "sister' in this chapter is his little sis, which didn't exist in ch1 (duh). Obviously his parents got working during these years. There's a 5 years timeskip.
Worse... he rewrites how to cast magic completely differently to the point where he can cast all elements, literally he's a true sleeper.... you think he's worthless on the outside, and once he starts, he blows away everything.
lol this chapter was TOO perfect! It had the rejected abandoned gold digger, Arel finally defeating his mom, the adoring imouto, the perfect waifu undergoing waifu training, and Arel finally learning magic as a classless! CRAZY!
@CrazyPotato you do realize you posted a picture of his elder sister whereas Mila is his younger sister
