Shikoku

Shikoku is a talkative person often making fun of Rairen for an assortment of reasons; from his failure to defeat Tenka, having to rescue him and mocking his initial plan against the Anti-Demon Corps. Unlike Rairen, who was rather hostile towards humans to the point of mocking the entire species, even Tenka who nearly killed him, she finds humans interesting, using a smartphone and taking on different modern poses.[1][2][3][4]

Despite her playful nature, Shikoku is tactical and careful, thinking and utilizing different plans to combat the Anti-Demon Corps, while maintaining her composure and advising Kuusetsu to be careful. But, she can also be surprised if a situation doesn't go as planned but still intrigued by the situation at hand.

She is also capable of becoming enraged and holds a great deal of pride in herself, becoming furious at a mere 'rank-and-file' officer managing to inflict a wound on herself. Shikoku also held her fellow Eight Thunder Gods in a considerable amount of affection and respect, saving Rairen and warning the others about her observation and even giving Kuusetsu warning and multiple Shuukis. This is further reinforced by how Shikoku was willing to humor the younger Gods' attempts and growing resentful after her demise.

Shikoku gained an interest in Yuuki after seeing him transform into a Shuuki-like monster after fighting against Kidoumaru to the point of making the effort into sneaking into his bedroom at the 7th Unit base.Little is known about Shikoku's background. At some point prior to the 7th and 6th Unit's exhibition match, she attacked and defeated several members of the Anti-Demon Corps' 3rd Unit.[5]Shikoku appears almost like a normal cute young girl of short stature, long purple hair that consists of snake tips, slitted eyes, sharp canines, and a black mark near the tip of her tongue.

Most of the time, she is seen dressed in a traditional Japanese kimono with her hair tied in the back using a red ribbon.As one of the Eight Thunder Gods, Shikoku is one of the eight strongest Shuuki, considered one of the "Gods" in Mato, likely being their leader. She also has complete command over the Shuuki horde, being able to manipulate thousands of them, forcing them to attack the Anti-Demon Corps, in addition to being capable of making several modifications to Shuuki, making them a lot stronger than before and creating a custom Shuuki.[6]

Darkness Manipulation: Shikoku has proven capable of using darkness-based powers, being able to transverse through shadows as she could rescue Rairen from Tenka's spatial attack, which almost killed him.[7]

Black Spiral (黒渦巻くろ うずまき, Kuro Uzumaki, lit. "Black Swirl"): She manifests a dark sphere in-between her hands, creating an attractive force that brings in anything in front of her.[8] Snakes: She can control the black snakes resting at the tips of her hair almost like an extension of herself, doing menial tasks such as messing around on a smartphone without using her hands,[9] extends them to ensnare her opponents and knocking even strong Shuuki out using a venom,[10] and regaining control of one of their Shuuki.[11] These snakes can also release poisonous gases from their mouths causing effects like hallucinations, which was potent enough to affect Shushu and Tenka for a time not being at full strength.[12]

Dark Snake Prison (闇蛇牢やみじゃろう, Yami Jarō, lit. "Dark Snake Prison"): Shikoku enlarges her snakes, which then wraps around her intended targets, in addition, to injecting them with a toxin potent enough to knock out two Humanoid Shuuki.[13] Immense Durability: As a member of the Eight Thunder Gods, Shikoku's able to take on a great deal of punishment. This is best seen where she took a hit from a gigantified Shushu and showcased no issues whatsoever. After getting kicked by Ren, she only sustained minor injuries.

Enhanced Endurance: Shikoku has considerable resiliency. After getting brutally impaled by a large sword, she still remained conscious afterwards.
