Personality
"Even side characters have their battles to fight."

- Cid Kagenou

Inspired by TV Shows and stories, Kagenou is obsessed with becoming the Power Within Shadows, a person who exerts enormous power from the shadows. He spares no effort dedicating himself to that goal and takes great pride in his achievements. He appreciates other people's hard work and disdains those who rob power.

His followers believe him to be a brilliant mastermind when in reality his success comes from dumb luck, improvisation, and his superior combat prowess. In his civilian persona, Cid hates drawing attention, portraying himself as a below-average student. In his Shadow persona, he is obsessed with appearing cool and mysterious in front of his followers, muttering ominous lines and performing silly antics. The Shadow Garden is extremely loyal to Cid, and some of its members are secretly in love with him, although Cid is oblivious to that. It annoys Cid whenever some of his subordinates take credit for the otherworldly knowledge they learned from him. He likes money and prefers to earn it himself rather than rely on the funds gathered by his subordinates. Despite being distant from his loved ones, he does care for them.

He is obsessed with making himself a mob character and allowing himself to be tortured by investigators for nearly a week because he feels it adds to his image as a mob character, even though he could have easily killed his torturers or simply used his knowledge of healing magic to recover from all the damage they did to him instantly. As long as he believes it makes him more "mob-like", Cid will happily allow himself to beaten black and blue, stabbed, and he one time stopped his own heart for 10 minutes for the sake of what he called a "mob saves the main character event".

Powers & Abilities
Cid Kagenou is an extremely powerful warrior, due to a lifetime of training in martial arts combined with his expertise in magic.
 * Martial Arts:

In his previous life, as Minoru Kagenou, he practiced various disciplines such as Karate, Boxing, Kendo, Mixed Martial Arts, Zazen, Buddhism, and Yoga. Around his teenage years, he reached peak levels of the human body and was capable of overpowering opponents who underwent military training.
 * Acquiring skills:

After being reborn into the Kagenou family, Minoru retained all of his past abilities while studying magic. This immensely augmented his abilities, turning him into one of the most powerful people in the world. In his civilian persona, Cid never displays his true power, instead, he practices what he calls Mob Fu, or the art of losing battles with style. As Shadow, he is skilled enough to simultaneously fight and effortlessly defeat Beatrix and Iris Midgar, two of the most accomplished Spellswords in the world. Iris regards Shadow as the strongest man in the world.
 *  Previous world knowledge:

Cid has refined control of his magic due to years of performing experiments. He can cure cursed children and vampires, as well as create slime suits and swords. Presumably, his body releases his mana at full power that explodes into a whirlpool of splendid violet light, petrifying normal people and affecting the weather.
 * Magic:

Other uses of his magic involve using wide-area detection magic, boosting an army's combat power and mind control. He can also strengthen the defense of his slime suit to the point that he remains unscathed after receiving an all-out barrage from Maximilian, someone who has similar quantities of mana.

He can make his ability that mimics a Nuclear Explosion into a large healing spell instead.
 * Healing wave:

His signature technique is  ' I AM ATOMIC!' , the result of all of his hard work to finally defeat his last challenge (of defeating a nuclear weapon) in where he pours much of his power into his blade into a devastating strike that once struck against its target, he or she will disintegrate followed by an explosion that can shake the land to pieces and even affect space.
 * Special technique:

It is implied that he can magically extend his lifespan to at least 300 years. He is more concerned about getting funds to live for 300 years (as he does not consider the money earned by Mitsugoshi Company as his own) and talks as if it is already set in stone that he will live for 300 years.
 * Longevity:

Outside of his combat abilities, Cid is a master actor who successfully portrays himself as a mundane individual. He is a skilled pianist who can play Beethoven's Moonlight Sonata and is knowledgeable in various sciences, to educate his closest subordinates.
 * Acting:

Trivia

 * His name on Earth was 影野実 (Kagenou Minoru). 野 could be just ateji to substitute の, so his name is the beginning of the series title "陰の実力者になりたくて" (Kage no Jitsuryokusha ni naritakute) with 実 being read as "Minoru"; alternatively, 影野 read together means "shadow field", as in Shadow Garden.
 * His family name is カゲノー (Kagenou). When read in Japanese name order, his name becomes "Kage no Cid", as in "Cid of the Shadow".
 * Throughout his training, Cid collected various rare and expensive items such as art and antiques from loots of various bandits he defeated.
 * Cid owes a meal to Alpha after eating her share of food she provided during the abduction incident involving Princess Alexia but has yet to receive an opportunity to return the favor.
 * Initially Atomic is written as Taepodong, the original author soon change it for political reasons to atomic.
