Bang! The trigger was pulled, the bullet was shot. However, Adachi wasn't the dull man people thought he was, so he dodged it.
"T-That was my only bullet, though," Nico sadly looked down at the revolver.
However, Igor produced a weird bazooka-looking gun from behind his back.
"Use this!" He shouted, tossing the gun to Nico. He caught it, his arms almost dragged down a little by the weight.
The four other delinquents stepped out of the way, and created a perfect range for Nico to wreak havoc upon Adachi.

Nico looked down at the gun. "…oh!" He laughed.
Igor took the gun from Nico politely. "I'll dispose of this man."
Nico smiled to himself. The deed is done.

Barely any darkness. Darkness, light, hearts…darkness, light, hearts…
