explosion guts

“Daaarashaaaaaaaaaaaaaaaaaaaaaaa!!”
When the pissed-off #7 yelled, an explosion formed with him at the center.
“You’ve just been doing whatever you want this whole time!! I won’t allow it anymore! I
will now show you what true guts are!!”
There was no real excuse for getting all worked up on his own like that, since his last
attack had knocked the delinquents out cold. The fact that he threw in additional attacks
made it a little unclear who the villain was. Haratani began calmly thinking that the
delinquents were the ones that were going to have to show true guts to get out of this.
