Steel Ball Run - Chapter 75
Diego explains to Hot Pants the mechanisms of Valentine's power as they observe him in the lead car, wondering at Lucy's transformation and understanding that she was the host for the Head. His marvel is cut short by Diego who attacks him. Diego and D4C briefly clash before Diego backs away, having injured Valentine.
When Diego explains that he will kill him without putting him between two surfaces, Valentine becomes anxious and tries to slam himself between a door and a wall. His escape is blocked by Hot Pants who detached her arm and uses it to stop Valentine from going into a parallel world. Valentine almost dies after D4C's hands are cut off, but a jar of water spills itself on him, enabling him to escape. A drawer suddenly opens itself on Hot Pants, knocking her on the ground, and several Valentines emerge to attack Diego.
Diego then unveils his trump card, forcing the three alternate selves to jump at him and the confusion their landing causes allows Hot Pants to use Cream Starter to disguise Diego into Valentine. Diego exploits the confusion to kill two Valentines in one move and goes after the last Valentine, who tries to jump through a window. Diego follows him and pushes away all the debris so Valentine can't escape, and then punches though Valentine's throat.
