The Infinite

The Infinite (ザ インフィニット Za Infinitto) is one of The First's spirits bound by her jujutsu technique. He serves as her most powerful spirit. Like The First, The Infinite also read the original World Trigger series, so he is allowed to act separately from her. He is the only other member of The First's group who was given the EX-rank regardless of his pact with her, as he has the most Trion out of anyone in Miden.
