of Deidoro Sakaki, and was able to take them by surprise, defeating the duo

Fifty-fifty then, Mirio was able to utilize the power of prediction and incredible brute strength to hold his own against the villain for v uninterrupted minutes while yet protecting Eri, until Overhaul was successful at immobilizing the de-powered hero, and the Nighteye Squad arrived to requite help to Mirio.

opted a retreat. Despite this however, even afterwards months of being without his Quirk, Mirio withal retains remarkable proficiency with his power in gainsay.

During his brief confrontation with Shin Nemoto, Mirio deduced that the con artist wasn’t the type of individual who would be on the front lines of battle, to which Shin admitted.
