Anivoice ( () (もの) ボイス Ikimono Boisu?) is the Quirk used by Koji Koda.


Anivoice allows the user to communicate with and command animals through speech.

This makes Koji a versatile hero due to the diversity of abilities found within the animal kingdom. For example, bugs with their small size and burrowing capabilities are able to perform sneak attacks from underground, birds are useful for reconnaissance due to being flying creatures with great eyesight, and so on. While Koji seems to be able to understand animal language to some extent or receive information from the animals he commands, he can't specifically communicate with any animal through intricate dialogue.

As part of his training, Koji engaged in vocal exercise to increase the range of his Anivoice, allowing him to control animals from long-distances.

In the manga, Anivoice is portrayed through a unique speech bubble, with undulated borders.


Animals must be within Koji's vocal range in order to be influenced by Anivoice. Humans, despite being animals as well, are exempt from the effects of Anivoice. This Quirk is also ineffective against artificial creatures that have been shaped to resemble real animals.

Anivoice is sound-based and, because of that, any noises louder than it (such as other sound-type Quirks like Voice) are likely to disrupt its effects, either by drowning out Koji's own voice or scaring away nearby animals. In addition, this Quirk is ineffective if Koji is unable to speak.


Koji is always polite with animals when requesting their assistance, with all his pleas having been met so far. Koji appears to have a great relationship with them, which might be a possible effect of his Quirk, as well.

Sometime before the Provisional Hero License Exam, Koji improved his Hero Costume with a voice-amplifying device, which he wears over his jaw. With this piece of equipment, the sound range of Anivoice greatly expands, allowing Koji to lead a large number of animals at once.

Koji is afraid of insects and other bugs, which somewhat hinders his communication with them.[1] Despite that, Anivoice works with those animals just as well as any other.
