Caubac Alcatraz

In Tsukihime:
Alcatraz is a magus who became a vampire through his magical research. He is an old friend of [Kischur Zelretch Schweinorg](https://anilist.co/character/185129), and he was one of the people present for [Arcueid Brunestud's](https://anilist.co/character/2213) birth eight-hundred years ago. He only met her that one time, but he left a lasting impression on her. He has been missing for over a century, and it is unknown to others if he is still alive.

In Tsukihime remake:
Prior to becoming a vampire, Caubac was a member of the Holy Church. He lost his heart thanks to the actions of [Crimson Moon](https://anilist.co/character/188970) shortly before the transition to AD, but Crimson Moon also saw potential in him and transformed him into an Ancestor. Around the year 1000 AD, he completed the [Holy Scripture Triten](https://anilist.co/character/72171). Caubac is called one of the "three idiots" who make up Kischur Zelretch Schweinorg's tea-drinking companions.

In Mahou Tsukai no Hako:
Mr. Cellphone is a Mystic Code through which Caubac Alcatraz interacts with the outside world.
