My Hero Academia has finally revealed the name of an important new quirk in Tomura Shigaraki's arsenal. The war between the heroes and villains continues with the newest chapter of the series as Tomura Shigaraki has reached his limits with his use of All For One. Although inheriting his master's quirk unlocked a great deal of powers and additional quirks within him, the onslaught of heroes has been so fierce that Shigaraki is barely holding himself together. It's led to him using a familiar quirk that All For One once used in the series' past.
