Eris and the Triplets enters the fray.

Just a little follow-up to the earlier picture, There's a difference between Kikoujutsu and Sorcery.

While Magic is an ability that can be learned but often gained or taught.

Sorcery on the other hand are abilities obtained from Inheritance and doesn't necessary needs to be learned.

Hiro is less mobile because it requires Ki for him to use an ability which can spend multiple amount of like energy and can cause his stamina to weaken.

He needs the stamina to fight in the front of the battle, Eris because of her traits doesn't need to waste energy except when using spells.

The other three the Triplets followed her to the area as expected.
