Io

Io is a Ranker and one of the hosts of the Workshop Battle. He is also the creator of the White Heavenly Mirror. He currently resides in the Archimedes, where he and Punk present and proctor the various events that comprise the Workshop Battle.

Personality and Appearance
Io wears a black suit with white gloves and is in most respects attired similarly to Punk. Unlike his partner, however, his helmet is blue and covers his entire face. He is often represented by the symbol seen on his helmet, which resembles a caduceus in a white circle.

Both he and Punk seem to enjoy their jobs and do not seem to have many scruples over harm caused to Regulars in order to complete their research.

Archimedes
He was first seen next to Punk, discussing the upcoming Workshop Battle and the items they had created. The two met up with Madoraco, who discussed how they might profit from the Battle. After he left, Io and Punk noted that the money could help complete their research into Emile.

Battle x Gamble
Io explains the rule of the tournament, is also in charge of announcing the gamblers and explain the rules of the upcoming event called "Plug". He played the role of commentator, entertaining the audience throughout the matches. When Ran proposed the change in rules, he was hesitant at first, but Madoraco ordered him to allow the change in rules as that was what the audience wanted.

The Truth
During the Archimedes Party, Io, alongside Punk and the other moderators, held a live performance. At the end of the concert he gathered all gamblers of the Plug event for a meeting regarding the results of the previous game, which caused the defeat of the majority of participants due to Parakewl's illegal intervention. Because it was too late to rewind the match between Anak and Ran, Io proposed a new set of rules for the participants. He proposed a Developing Tournament in which all of then accepted the new rules.

Trivia
His appearance is based on that of Thomas Bangalter, a member of the electronic music group Daft Punk.
