[Crossover] □□ Big Shot, What Does This Have to Do with Me?

This is a future changed by an "outsider."

A girl named Asakawa Yumeno has taken away all of Sawada Tsunayoshi's "glory."

This is Namimori without Sawada Tsunayoshi.

And Midoriya Izuku has gained a brown-haired childhood friend.

This is a world without the mafia.

Yet the artificial merging of worlds has created a colossal power capable of influencing both the underworld and the legitimate world.

This is a Vongola that has lost its Tenth.

And the mystery surrounding this leader, who has never once appeared, only makes people fear and wonder about him all the more.

This is the story of a good-for-nothing who rises to become a hero.

But all sorts of strange people keep getting tangled up with him, completely derailing his plans.

[You will be my unchanging faith for all my life.]

[I miss you so much it hurts.]

[Ah, please grant me the honor of your devoted embrace.]

[Please give me the courage to keep living in this world.]

? This is my first time writing a story, so I'm posting the first chapter to test the waters! If anyone reads it, I'll keep posting!
