Vines

Vines is the Mutant Quirk carried by Class 1-B's Ibara Shiozaki, rated at medium range. It appears in Chapter 35 and Episode 21, and the series later notes its kinship with Arbor, since both grow and command plant matter produced by the user's own body. Kamui Woods is among the characters who make that connection out loud.

Thorned creepers replace Ibara's hair entirely, and she directs them at will. They serve as restraints for enemies, as arms for retrieving objects at a distance, and as improvised walls when something needs blocking. She can also sever them from her scalp whenever she chooses, and they are sturdy enough to bore through concrete.

Their thorns cut. The Joint Training Battle left both Eijiro Kirishima and Denki Kaminari scratched up, Tetsutetsu had to harden his arm with Steel just to carry her without being scraped when the Vanguard Action Squad attacked. She has also feigned worry over a mark her thorns left on Yui Kodai's back. The vines also refuse to conduct electricity, which gives her a built-in advantage over Electrification and similar current-based powers.

They are not invulnerable. Tough as the growth is, a sufficiently sharp edge will cut through it, and the vines depend on sunlight and water to keep growing.

Her named techniques lean on volume and coverage. Via Dolorosa floods a whole area with creepers that snare anything brushing against them. Crucifixion wraps a target that has already been caught in layer upon layer of vine until they cannot strike back. Faith's Shield raises a dense barrier in front of her to absorb an incoming attack.

Ibara Shiozaki alone holds it, and it shapes her reputation at U.A. Her win over Denki Kaminari is the clearest demonstration of the electrical immunity, since his Electrification simply had nothing to travel through. Across the Joint Training Battle and the Vanguard Action Squad Invasion, the Quirk repeatedly proves itself as much a control and defense tool as an offensive one.
