Eikichirō Saidō

is a Shinigami.

Personality
Saidō seems to be a bit lecherous, due to him commenting on how he had a clear view of a soul's panties in the Fake Karakura Arc, as well as making up (rather lewd) reasons for why Rukia decided to stay in the Human World, the main reason being how she was looking for "pleasures of the flesh", however, he also seems to be quite level-headed and kind, as seen when he was playing with some children in Rukongai.

Agent of the Shinigami arc
While he is playing spinning tops with some children, a Shinigami approaches Saidō, telling him that he has come regarding "No. 13", Rukia Kuchiki. Hearing the name “Kuchiki”, Saidō laughs and asks what "the little princess" has done. The other replies that she has exceeded the time limit for staying in the Human World, and that there may be more beneath the surface for Saidō to investigate. He is told to leave right away. Saidō arrives in Karakura Town where he finds Rukia. Despite being two years Rukia's senior, Rukia states that she has never seen him before. Not long after his arrival he found himself pressed into service assisting Rukia and Ichigo Kurosaki against the Hollow, Grand Fisher. After being wounded by Grand Fisher, he fell asleep. However, he witnesses the conclusion of the battle and sees Ichigo defeat Grand Fisher. After Ichigo loses consciousness, Saidō comments on Ichigo's potential and decides to leave Rukia alone.

Fake Karakura arc
Saidō is later put in charge of the area around Kagamino City. After a group of Hollows chasing the soul of a young girl are destroyed due to the sheer Reiatsu of the Shinigami and Espada, Eikichirō notes on the beginning of the battle but also wondering who will win.

Powers & Abilities
Expert Swordsmanship Specialist: Saidō is very proficient in Zanjutsu, able to easily overwhelm an inexperienced Ichigo Kurosaki when he (Ichigo) first became a Shinigami.

Hakuda Combatant: Saidō showed respectable skill in unarmed combat during his brief fight against Ichigo. He would use powerful kicks whenever he found an opening.

Perceptive Combatant: Saidō is somewhat perceptive as he was able to determine Ichigo's combat abilities, which involved relying solely on brute strength rather than the skill and finesse of swordsmanship.

Spiritual Power: As a Shinigami, Saidō possesses some spiritual power.

Zanpakutō
Saidō's Zanpakutō appeared to be a wakizashi with a black hilt and gray guard. Due to his brief appearances it is unknown if he is capable of performing Shikai or able to communicate with his Zanpakutō.
