Sekito Sakuraba shows up as a transfer student with an air of mystery about him. He rescues Kaito and the crew pretty early on, which immediately makes you wonder who he is and what he's doing there. Turns out he's got insider knowledge about the black Hero Suits and the Tower of Seizure—information he shouldn't realistically have. Fans often speculate about what his actual connection to these things really is, since he clearly knows way more than a regular transfer student would.
