The so-called mastermind behind the foul play of the Mass-Divers. He intends to destroy GBN by dispersing the unofficial tools he has developed, known as Break Decals. His hatred for the GBN, which he calls a world full of "lies" and "deceit" amongst other things, stems from the fact that the popularity of GBN led to the obsolecence of the GP Duel, an older system for playing Gunpla Battle, which he considered to be more representative of a real Gunpla Battle. Tsukasa is also a former friend of Koichi Nanase, and Ayame's master before her defection.

Tsukasa Shiba is shown to be a masterful gunpla enthusiast and veteran battler, having experience with both GBN and GPD; the latter with over 500 battles. It is also heavily implied that Tsukasa is a skilled programmer; as he is the creator of the virtually-undetectable cheating tool - Break Decal.
