Shirou Yusa

Summary
Ren's best friend since childhood. He is a genius skilled in all sorts of fields, but as a result, he finds life boring. As a constant thrill-seeker, he acts recklessly and even incited a brutal fight with Ren, ultimately breaking off their friendship. As a result, he vanished from school and has not been heard from since.

He later reunited with Ren and made amends with him by fighting alongside him against Reinhard and the Longinus Dreizehn Orden, becoming his Apoptosis later on.

Tenma Sukuna is given protection by Yato Time Armor, but should he move farther away from Yato influence, he would get weaker.

Notable Attacks/Techniques:

Yetzirah

 * Elizabeth Bathory: During the events of Kei and Maries' routes, Shirou obtains Rusalka's Holy Relic (either by Mercurius granting him it in Kei's route, or forcibly taking it away from Rusalka after the latter tried to devour him in Marie's route). In Shirou's use of the Holy Relic, he is capable of summoning them off from his own body such as: summoning chains from his arms that can reach up to twenty meters and exert a pressure force of ten tons, grant his desert eagle gun the same attribute as all Holy Relics (meaning his bullets can now deal damage to the soul), and can create an iron maiden-like cage out of his chest cavity capable of tearing off limbs from any who happen to be unfortunate enough to get caught in them.

Atziluth
Notable Attacks/Techniques: Note: Tenma Sukuna (and the rest of Yato's legion) have never been shown at full power as they were sacrificed to restore Yato's Taikyoku back to 100 when he was weakened to 70 so Sukuna would logically be stronger than when he was a part of Ren's Legion.
 * Malignant Tumor Apoptosis: Shirou’s Atziluth, used only when he's risen to Ren's level as a Pseudo God. This ability allows Shirou to crush all supernatural abilities in his vicinity. It works on anything supernatural, from Distortions/Briahs to even the Taikyoku of other Gods, allowing him to harm even the likes of Reinhardand Mercurius during the final battle in the Three Colors Route. However, due to his connection to Ren, one can escape and bypass this either by being superior to Ren, or by being a normal human (by which point, the ability will turn on its owner as the only supernatural being present and thus bring him down to the level of a normal human).
 * Malignant Tumor Apoptosis: Tenma Sukuna's Taikyoku version of Malignant Tumor Apoptosis, which can nullify anything that is supernatural around it's vicinity; even nullifying the Taikyoku of other Gods, bringing them down to the level of a normal human. The only way to nullify this ability is to have an equal or higher Taikyoku value than Yato or be a regular human, upon which the ability will turn on Sukuna instead, rendering him powerless in the process.
 * Kamunagara: Physical Manifestation of Hadou God Law, having an universe inside them, the Kamungara of Sukuna takes the form of a giant demon with two heads.
