Shiba didn't have enough by killing the weakest of the three Rank 8 experts.
However, he knew that the other two would be harder to deal with since they were already wary of him, and they were stronger than the other one.
Meanwhile, the two remaining Rank 8 experts stared at Shiba with a hint of fear.
They knew that Shiba was the academy's deputy principal, but they didn't even fear the principal, a mere deputy principal at Rank 7 didn't mean anything for those Rank 8 experts.
However, Shiba's attack hadn't been something that a Rank 7 expert could do, so they needed to reevaluate their opinion of Shiba.
They wondered why someone at Rank 7 was together with Shire and Eini since he would be useless, but it was obvious that Shiba wasn't a mere Rank 7 expert.
Of course, they still didn't know that the Annihilation Flame Tornado needed both Shiba and Eini.
