[Anime Crossover] I Don't Want to Survive in the Zoldyck Family Either

A heroine steeped in black sludge, gradually going mad, mad, mad, until she becomes black sludge herself. First-person narration.

I was a twenty-first-century female university student, a flower of the Panda Nation who had just gotten into graduate school. I opened my eyes, and I'd transmigrated.

I heard that my family was a notorious clan of assassins, and everyone in the family was a killer except the grass growing on the ground.

I also had a long-haired older brother named Illumi, who often appeared beside my bed in the middle of the night and scared me into wailing and crying. Milluki, who shared my room, would wail along with me.

I thought my life would go on peacefully like that, until my mom started feeding me poisoned formula and I foamed at the mouth.

It felt like something had shattered.

It was my heart.

I began to go gradually insane, gradually fall apart, gradually dare to jump up and fight my mom, screaming at the top of my lungs along with her. I gradually started fighting my brother, too.

Then came my brother's special training. Training, training, training. I was electrocuted and beaten until I was half-dead.

And so, I gradually got used to that life and became part of the Zoldyck family.

My brother's training broke my bones with a single punch. No problem. I spat a mouthful of bloody spit in his face.

My mom went berserk, screaming and scratching me until I was covered in blood. No problem. I yelled at her and called her crazy.

We were a happy family.

Then I transmigrated again, this time as a Zoldyck, and ended up in some unknown place. There I met a white-haired guy wearing sunglasses who looked like Killua and insisted I become his student.

Life here is so warm. Sometimes I want to stay here forever. At night, in a daze, I always feel like my brother is going to come and drag me away.

Until one day, my brother really did find me. He stretched out a hand toward me from far away. "Yuni, it's time to come home."

Premise: Fight to stay alive and slap everyone in the face.
