My Little Sister Was Isekai'd, I'll Tear This World Apart to Save Her!

Twenty years ago, my little sister was kidnapped by another world's summoning spell.



Twenty years later, I’ve finally hijacked my way into that world!



And now, I'm searching for her.





Angels?

Demons?

Gods?

Or even Fate itself?



So what? I don't fucking care!



I will find my sister, even if I have to tear this world apart!

Read this story if you are looking for:



- A genuinely smart main character who wasn't a loser in his past life and doesn't get spoon-fed too much superpowers or cheats. He becomes strong through sheer willpower, overcoming hardship, and outsmarting impossible odds, winning seemingly unwinnable fights.



- A harem, but not the typical kind. The main character won't chase any girl like a literal simp. Also, the girls aren’t flat, two-dimensional tropes either. Each has depth, distinct personalities, powerful backstories and real emotional impact on the MC. Also, the MC is mature, so expect meaningful and serious relationships, not the cringey, child-like and meaningless romance drama.



- A thrilling and well-thought-out plot filled with betrayal, deception, mystery, and plot twists at every turn. Friends become enemies, enemies become allies. Even those who seem trustworthy may later reveal their true, wicked nature. In this ruthless world, everyone has their own ideals and goals, and the line between good and evil isn’t always clear.



- No yuri.



- A unique blend of isekai, western-style cultivation, and even regression plot.
