Lastest chapter from Novel reader here.
He will never change from his Beta personality.
Last chapters, those assholes injure and use his sister as a bait and that may even die. And as you can see, he doesn't even do anything to them. Do you really think he will do anything to a man who "merely hits" his female classmate?
Bad thing is: he will never use "legendary gamer skills" willingly.
He'd rather let everyone being mistreat the whole way.
I has a feeling that he'd rather let everyone die than let people know about his power and knowledge (as you can see, he still care about his secret when his sister's life is on the line). And he will repeat it more than once.
He only cares about his family and some girls he loves and only moves when they are about to die.
As you can see, he did use his legendary gamer skills in the last fight to solo the boss to save his sister.
He will fight against Devil-reincarnated high level Player (Wrath) while he is still under level soon.
Yes, he is but a middle level player (Glutton) solo the boss (Wrath) who is also a ranked player.
Thankfully, the Devil is a true-bro and a true-fan, unlike him, so everyone is alive and well (even when the Devil loses his mind due to Wrath's skill, he still doesn't hurt his worshiped waifu).
Why can't we have this guy as main character instead?
I think the main heroine is his sister (As you can see, she appears everywhere and becomes the strongest female character now)
And other main casts:
another reicarnated female player (Lust),
The nice female knight who helps him and his sister before (who is cursed to be Fat/overweight) (He knows about the curse and how to break it, but rather keep it a secret or people will know about him)
An U.S female spy in his class
His mother (lured by him that raising level make her more beautiful)
And his father (also lured by him)
