The Ultimate Romance Conquest [Crossover]

Tenshinin Ayane was born a frail young lady, congenitally weak and prone to illness.

Frequently rushed into the operating room and kept alive by medicinal tonics, she made a wish to God:

"If you give me a healthy body, I'll do anything."

God heard her prayer and gave her the [Strongest Survival] System.

Through the System, she can travel between different eras and seek out the strongest people of each age.

Once she wins over each strongest person, she will gain the energy needed to heal her ravaged body.

And so, the beautiful young lady, so weak and powerless that a few steps leave her gasping for breath, has to take on different identities and pursue the strongest people of their respective worlds to gain energy.

But God never told her that those strongest people would eventually gather in the same world...

Leaving Tenshinin Ayane to face an awful reality:

How is she supposed to explain that she's come back to life and suddenly has several ex-boyfriends who have turned evil?

Her ex-boyfriends include:

The strongest King of Curses, Ryomen Sukuna

The strongest sorcerer, Gojo Satoru

The strongest ability user, Nakahara Chuuya

The strongest godfather, Giorno Giovanna

The strongest swordsman, Tsugikuni Yoriichi

Tenshinin Ayane: Maybe it'd be easier to just die after all!

[Strongest Survival] System: You earn survival points by winning them over. Host, won't you give it another try?

Pairing: A psycho, corrupted ex-boyfriend x a beautiful, frail young lady
