Tate Karito

Tate Karito is the mysterious 'Shield of Aegis'. He's a bodyguard who will protect anyone who can pay his price, regardless of the reasons why.

Tate and his agent, Anna Riddle, are crossover characters from Kyoichi Nanatsuki's 2000 manga, Aegis in the Dark (Yami no Aegis). Nanatsuki also wrote JESUS, the origin story for the titular assassin Jesus, who also appears in UDDUP.

Character
Not much is currently known about Tate. He used to be a member of Japan's Special Assault Team, and sparred in the same dojo with Genda. He is shown to share the same feelings of loss with Haruka. He also does his job efficiently as a bodyguard by diverting the attention from his charge to himself.

History
Tate was a member of Japan's Special Assault Team (SAT) until he left after marrying and having a son, as the SAT consists solely of bachelors. However, his name was leaked in a list of SAT members, and shortly afterwards lost his wife and son to a terrorist attack. His wife was shot and killed instantly, but the attacker&mdash;a man known in the underworld as "Butterfly"&mdash;strapped a time bomb onto his son. As Tate attempted to diffuse it, the bomb went off, killing his son and destroying his right arm.

Story
By the request of Daiba, Tate protected Komura from (probably) being mutilated or murdered by Mamoru.

When he went to get his arm repaired, Genda saw him and revealed that he had met Tate in the past.

He appears in chapter 110 in the Tea Room Siren, going over information on Edge Turus with Genda and Masuda.

Other Appearances
Aegis in the Dark, written by Kyoichi Nanatsuki, focuses on Tate Karito and Anna Riddle through various short stories about clients Tate is hired to protect. It is set several years before their Until Death Do Us Part appearances. Its 2007 sequel, Aegis in the Dawn (Akatsuki no Aegis) follows a similar story structure, but they are about the same age as their UDDUP appearances.

The duo also appear in Nanatsuki's final work set in that universe, JESUS Sajin Kouro, which elaborates on the Aitou Academy arc and ends with Jesus, Mamoru, and Tate's attack on 24 which was brought up in UDDUP Chapter 154.

Abilities
Tate's been trained heavily in martial arts. His primary weapon is his artificial arm, which he uses to deflect, and often catch, bullets. His skills have been shown to be on par with Mamoru. In addition to this he is also trained in the use of firearms, due to his time on the SAT.

Anna Riddle
Several years before the series begins, Tate was hired to protect Anna from those who sought her ESP. She collects jobs for him at the Tea Room Siren and deems whether the client is worthy of his services with her riddles. Their bond is extremely close and Anna trusts him enough to jump off a high ledge to him after being taken hostage&mdash;something not even Haruka, who was in the same situation, had enough faith to do.
