Yudaikus Tholoide

Оригінальне ім’я: ユーダイクス・トロイデ

Another of Astral's founders and former board member. An alchemist. Another one of the three people responsible for making Itsuki's eye patch. He is not human and is actually a mechanical doll (Automaton) made by Tsukasa Iba. After Tsukasa disappeared, he pulled out from Astral to chase after Tsukasa and also to advance his research. In the alchemist incident, he magically duels with the present Astral members to take back Astral from Itsuki. After that, he left for Egypt with Lapis. His leaving Astral is under examination by the Association. He later reappears again in London during the Ophion incident.
