Professor William vs Hiro Ernest

"Looks like I have no other option!"

Judging by Professor William's character and his actions, Hiro knows that the further he tries to talk to Professor William, the worse his mood will become.

[ "Devoted Star: Limit release" ]

Hiro's rank was already on the verge of breaking through to Rank-B -. With Limit Release, Hiro's stats increased and were on par with Rank-B +. Though Hiro doesn't want to stay in this state for much longer as its side effects are quite severe.

While Professor William was using his full power, however, he was not using any Art which made his punch less destructive though a Rank-D person would instantly die if he happened to take the punch.

But for Hiro whose power was that of Rank-B peak, it was nothing more than how a normal person perceives a punch from a normal person.

Hiro also used the mana-enhanced punch to counter Professor William's punch.

-SMACK! -BANG!
