Tatemiya Saiji
Heh heh. What are you doing, Anglican priest? C'mon, what happened to your pride as an English gentleman? Show it to me. Show it to Tatemiya Saiji. You've gotta do better than that or you won't be able to protect even a single girl.
~ Tatemiya Saiji to Stiyl Magnus


Tatemiya Saiji is a magician and the Substitute Supreme Pontiff of the Amakusa-Style Remix Church, leading the sect on behalf of their Priestess Kanzaki Kaori after she left them in order to protect them from the risk caused by being close to Saint. As Substitute Pontiff he and the Amakusas went on missions which carried the ideals that their Priestess believed in, and that is to always aid those in need. After a conflict with the Roman Catholic Church where the Amakusa and Kamijou Touma ended up saving Orsola Aquinas from them, he and the other members of his sect joined Necessarius for protection. He later willingly steps down from the position after Kanzaki Kaori returns to them and becomes their Priestess once more. An amicable man, he is a reliable ally of Kamijou Touma and has risked his life for him and other innocent people on many occasions.

Notable Attacks/Techniques:

  • Amakusa Style's Magic/Combat: As a member of the Amakusa-Style Remix Church, Saiji is able to use a mix of Christian, Buddhist and Shinto spells. The Amakusa are particularly skilled on a brand of Idol Theory that allows them to cast spells using symbolism hidden in body movement and everyday items.
    • Offensive Spells: Saiji can use magic to empower his sword strikes, allowing him to split the ground or to destroy a large section of a wall with a single blow. Also, with just a swing of his sword Saiji can launch a magic projectile that looks like a transparent snowball the size of a soccer ball. The snowball completely vanishes after hitting the enemy.
    • Movement Spells: Saiji can use magic to improve his speed without even moving his feet as if he was skating on ice. He can move fast enough to create an afterimage and cause Touma to think he had punched through an actual illusion.
    • Defensive Spells: Saiji can use anti-impact spells to defend himself from physical attacks.
  • Flamberge: Saiji wields an 180cm Flamberge, a 17th-century dual-handed sword. The unique characteristic about the flamberge is its undulating blade akin to a flame. It would normally be made of steel, but Saiji's blade is pure white. Touma couldn't tell what the blade was made of, but it certainly didn't appear to be metal. Despite its size, Saiji can casually wield this sword in one hand. The sword itself isn't magical, and as such can't be destroyed by Imagine Breaker.
    • Suppress Flame: An anti-flame spell apparently unique to Saiji due to his weapon. By removing the flame attribute of the flamberge and swaying the sword around like a river he can suppress a fire/flame attack, like Stiyl's flame sword or an explosion, and then send the heat and flames back to the enemy as a counter.
