[Crossover] Illumi Suddenly Changes Gender

Illumi was a boy.

At least, that's what Illumi thought before he turned fifteen.

Then one day, Illumi woke up to find two things on his upper body that shouldn't have been there, and one thing missing from his lower body.

Illumi fell silent.

Illumi tapped his left hand with his right, his expression blank, yet somehow looking as if he had suddenly understood.

Yeah, he must still be dreaming...

After checking himself over, Illumi continued to wear his blank expression.

There was no Nen wrapped around him, so it didn't seem to be caused by a Nen ability.

Right, he'd go ask Father.

"Aaaaaah!!!!" Kikyo squealed with excitement.

Illumi, forced to keep wearing frilly dresses: "..."

Hunter Exam

Killua: "Hisoka, aren't you afraid of my big sister?"

"Hmm~?? Who?"

"Illumi..."

Hisoka turned to stone, and his playing cards fell from his hand.

Hisoka was so astonished, he didn't even add his usual symbols. "Little I?"

"Oh-ho-ho??~"

Illumi transmigrates into the original story and takes the Hunter Exam.

"Killua, you really haven't noticed all this time..."

"B-Big brother? Sister?"

The swell of Illumi's chest made Killua change how he addressed him mid-sentence.

The astonished magician, Hisoka the fruit farmer.

Astonished... Okay, maybe it's not obvious? Illumi Zoldyck.

His lines get stolen.

Right, fifty million... one hundred million jenny.

"Killua."

Illumi Zoldyck pulled out a nail.

Killua was horrified, again and again.

Two "big brothers," twice the pain.

Naruto

Illumi: S-rank rogue ninja, member of the Akatsuki. Yeah, valuable.

Illumi blinked and tilted his head.

Would it be like the Phantom Troupe?

Theme: Stay true to the characters.
