Alektor

Alektor (卵の冠（アレクトール）) is Hairein's Black Trigger.

Functions
It enables the user to create various animal-shaped bullets out of trion, which are controlled remotely by an egg-shaped core used by the trigger wielder. These animals can be used for various purposes, such as forming shields to protect the user, or, upon touching anything made of Trion, cubification (キューブ化). Its main weakness is that can only affect things made out of trion, so the opponents cannot be attacked if they are in their physical body.

Some of the animals seen include fish, jellyfish, lizards, birds and even small insects such as bees.

Trivia
