————— Mission: grab mikasa’s ass Reward: Add 4 to your strength Add a random talent Punishment for not completing: your dick will get cut off Completing it: she might start hating you —————- Looking at my system I can’t believe this absurd shit Notice: please don’t take this fanfic seriously! There is gonna be some netori and incest.... This is a fanfic focused on hentai as well as some fighting scenes (especially in bed) Also there is some lolicon? Just some kissing between mc and mikasa that’s all.....everyone seem to be hating on that on the review, but I don’t care......fbi got my back that I’m not a pedo

When I died I didn't expect to wake up with dark beings of immeasurable power looming over me. I didn't expect to be given new life in a brand new world. Now, armed with a powerful system that makes me stronger after every fight, I might be the last thing standing between the multiverse and absolute annihilation. As I complete quests, defeat foes and become stronger, I still don't know if I'll be able to save this world, my old world and all the worlds in between. "And below... the MAW beckoned..."

Rakesh was an average boy who died in a Truck accident, However, that was not the end at least for him see how he gets reborn as Eren Yeager and changes the course of event .

Our MC, Asriel who is a 20 years old university student, after reading the latest series of attack on titan (by latest I mean the one where Mikasa was treated like shit) he felt extremely sad and angry about how the plot is going decided to go out and vent. Little did he know he would get the chance to change the fate of those characters. Also spoilers alert! Please read at your own discretion. This is my first time writing and just writing for fun. And because I feel really really sad about Mikasa's fate. (I wrote this when that chapter came out so.....yeah) This is a work of fiction, I claim no ownership or credit regarding the existence of pre-existing characters or content or plot or story and whatnot, except the original characters.

I die and was given a second chance in the world of attack on titan as a bender.
