Cid kagenou/shadow (TEIS)

Genius (Cid created the slime suit that is super light, silent, supports your movements and has killer defenses. He also created a cipher with five different languages. He learned everything from karate to boxing, from fencing to mixed martial arts, before reincarnate. After reincarnating, I thought that the sword style of someone who had mastered the Royal Bushin method was clumsy. Grease, who is a skilled knight, felt like a child in front of Cid, despite having with more power, Cid faced him only with skill. His swordsmanship does not depend on strength or speed, but on the basics, which can even defeat geniuses. He copied Rose's swordsmanship after seeing her once. He can see the purpose in the smallest actions, like a tremor at the tip of a sword, a change in gaze, the position of the feet and preparing a superior response. Has the ability to think through battles, viewing the battlefield from above with a keen eye to understand the progression of a fight and predict its future developments. He can analyze his opponents with just a glance and refine his movements in a fight, making him have to run away less and giving him more chances to counterattack. His swordsmanship is polished to the point of art, being great enough to make him known worldwide, and yet this isn't even his true swordsmanship as Shadow, just a sophisticated sword style made to be performative. This sophisticated sword game, which is not even your real sword game, is a unique and incomparable masterpiece, mixed with the best parts of countless other martial arts, and is at a level that not even centuries of training will reach. He reached the peak of his martial skill, being able to dodge attacks by walking, making microscopic movements. His attacks are natural; There is no bloodlust, no hesitation, no arrogance, so people cannot perceive them, just as they are not actively aware of the falling of individual raindrops. Through sheer skill.

Vaporizing 1 building equals 1.70 kilotons of TNT), greater over time Speed: Relativistic (0.7c.

His personality is described as someone between the ages of nine and 15, as he has "8th grade syndrome", known as 'Chūnibyō', people who have delusions and believe they are unique and powerful beings and possess hidden knowledge. These delusions were inspired by TV shows, video games and other stories, making him obsessed with becoming the “Eminence in the Shadow”, a person who wields enormous power and influence in the darkness of society. He goes to great lengths to dedicate himself to this goal and is very proud of his achievements. He appreciates other people's hard work and despises those who simply lend their strength.
