(A/N: Requested Zexalsaiyan4, and it's actually Male reader yuuki x yandere caring kyouka, himari, nei, shushu, Tenka, Sahara, yachiho , aoba, yuno, and koko (lemon). And also, it's an alternate universe.)
(Y/N Wakura is a boy who wanted to become a hero, and his kindness and caring attitude are supposed to be the key for him to achieve his dream, but once he met the Anti-Demon Corps and the Humanoid Shuukis, they fell in love with him and swore to do anything for him.)
Aoba: Oh, onii-chan. You're so handsome... so caring...
Koko: We will protect you from any harm, okay?
Yuno: We will do anything and everything for you.
(Suddenly the Anti-Demon Corps Girls: Kyoka, Himari, Nei, Shushu, Tenka, Sahara and Yachiho come in.)
Shushu: Hello, sweetie.
Tenka: Did you make sure slave-kun behaved?
Aoba: Yes, onii-chan was well behaved.
Sahara: Good. Now let's make Y/N more company to make sure he doesn't get hurt.
(Then Kyouka and Himari smirk as they press their boobs on his chest.)
Kyouka: Tell me, dear slave. Have you been a good boy?
Y/N: Look, I can handle myself.
Himari: We just don't want you to get hurt, that's all.
(Y/N blushes, causing Kyouka and Himari to giggle.)
Y/N: Well... it's getting late. Maybe I should go to bed.
Nei: Not without us. You can't.
Yachiho: Let's go!
(Then they take Y/N to their room, and strip naked before removing his clothes and see his erected member.)
Aoba: Oh my, happy to see us already?
(Nei and Yachiho lick his member while creasing his balls. Aoba sits on his face and has him lick her. They go faster, and both Y/N and Aoba cum. Then Kyouka and Himari take their turn.)
Kyouka: Ready, slave?
(Then Kyoka inserts Y/N's manhood into her womanhood while Himari sits on his face, having him lick her.)
Kyouka: You're as big as usual.
Himari: And good with your tongue.
(Y/N licks Himari more.)
Himari: More
(Y/N licks Himari more while Kyouka bounces faster, and the three eventually ended up cumming.)
(The girls had Y/N to themselves, and occasionaly killed anyone standing in the way of their love.)
