Tsukuyomi (Teshun Strife)

Teshun Strife, also known as Tsukuyomi of Emiyo was the familiar of magus Emiyo Asaka, until his ultimate sacrifice to save his master's original mage team against Amaterasu. Born Shun Maio, the familiar lived a normal life to a normal family until a fated encounter with a factory explosion that destroyed his body. In an attempt to take over Shun's body, which was left extremely vulnerable to possession, the abyssal beast Oni emerged from the shadows to merge with the boy, however was half successful as a chain reaction explosion destroyed Oni's consciousness. Reborn as an Abyssal Recombinant, or a failed possession product, Shun gained enormous umbral powers akin to Oni, while keeping his humanity.

Growing out his hair, and changing his wardrobe upon discovering his new overwhelming powers, Shun changed his name to Teshun "The Tsukuyomi" Strife, in an act to start life anew as a "super cool hero of the night". However, due to his powers being "too powerful", Teshun became overwhelmed with boredom, and lacked the will to do anything with his life, leading to him leading a lifestyle as a shut in NEET.

At some point, Teshun discovered his ability of Shadow Manifest, in which he began making counterfeit dollar bills to purchase assorted snacks in the local convenience store. On his way to purchase the newest "Barbeque Hamburger Limited Edition Potato Chip", Teshun ran into mage battle maiden Emiyo Asaka, who was being pursued by The Berserker, a contracted brute that had killed three of her team members and enslaved two. However, Teshun paid her no attention until the shockwaves of The Berserker's attacks knocked his chips to the ground, spoiling them. The resultant shock caused Teshun to angrily engage The Berserker, killing it with overwhelming force, much to Emiyo's bewilderment.

Teshun offered to become Emiyo's sidekick, becoming infatuated with her, but was instead turned into her familiar due to Emiyo witnessing Teshun's enormous power. However, due to Teshun's laziness to do his job properly, Emiyo has since regretted making the contract, frequently calling her familiar Tsukuyomi the Worthless.

Appearance

As Shun Maio

Shun possessed a scrawny build, with a pale face, and long black hair that reached his chin and his back similar to a mullet. A running gag during his high school days was that Shun was often mistaken as a girl from behind. Shun wore large eyeglasses and was often self conscious with the size of his eyes, believing them to be too small. In an attempt to grow out his hair to cover them, Shun often combined his hair to the front of his face.

Shun refused to wear anything but black, as he was obsessed with the comic book superhero Tsuku, who's powers were black electricity. Frequently wearing black hoodies and black track pants, many of his peers believed him to be an "emo".

As Teshun "The Tsukuyomi" Strife

After discovering that the extent of his powers were largely based on how well his body could withstand the darkness flowing through it, Shun underwent physical strength training, and gained a powerfully built physique. Changing his name to Teshun Strife, and adopting the alias of Tsuyukomi, Teshun often wore a dark blue fur coat, the fur around his collar a light beige. He also wore a pair of black jeans, and a black tank top, which exposed his musculature (which was intentional to show off the results of his training to Emiyo).

In addition to this, Teshun frequently wore a white mask that covered his face, as, although being capable of shape shifting, Teshun's default appearance was still very similar to his old appearance as Shun Maio. In comparing his face to his body, Teshun became self conscious that he was "not good looking enough", and resorted to growing out his hair and covering his face to give him an appearance that would "resonate with the ladies".
