Rei Rakuyo

Rei Rakuyo is the current Lieutenant under Captain Lisa Yadomura and former 5th seat under Shunsui K before he was appointed Head Captain.

Personality
Rei is a rather quiet girl, known for her dutiful, responsible, and respectable behavior. She got along well the former Lieutenant and Captain and helped regularly with paperwork. Though when only the 5th seat, it was an unspoken rule that she was in charge is the Captain and Lieutenant were gone.

Rei is easy going, but isn’t afraid to let her temper loose. Head Captain Shunsui describes her as “small, but fierce”. She is known for giving Shunsui lectures and was part of the “Hard Trifecta” along with Lisa and Nanao. She is a stickler for those that refuse to get stronger as she believes that anyone can grow.

Rei seems to be immune to Lisa’s perverted tendencies and tends to intercept her when she is about to act out of line or say something weird. Though, she has shown to lose her patience after finding dirty magazines belonging to the captain all over her office. She and Captain Lisa has a strong relationship being able to read each other’s movements and actions in battle as well as trust the other explicitly. Their unison in battle has been noted as the best among the 13 squad captains and lieutenants. This is due largely to their calculating minds.

Within Division 8, Rei has the reputation of being the tactician. She is proud of her accomplishments of rising Squad 8 to the top contenders in the Gotei 13. Her intelligence rivals the best and most experienced in the Goeti 13. The former captain head-hunted her after seeing her potential noting that she reminded him of Captain Hitsugaya.

Due to this, Rei places high expectations on herself. It was her inability to control her Bankai that lead her to reject the offer to be Captain of Squad 8. She felt that she wasn’t ready for the role and agreed that Lisa was more suitable for the job.

Zanpakuto
Ōkaze (大風, Great Wind) When sealed, Okaze looks like a katana with the exception of the guard, which is in the shape of a silver spiral. Its hilt is orange, and sheath burnt orange. The sheath completely dissolves when Okaze is drawn. The sword is somewhat longer than most Zanpakutō, at about 1.4 meters long. This makes it taller than Rei, preventing her from wearing it at the hip. Because of this, she instead carries it on her back by her pink sash over her right shoulder.

Okaze is the strongest of all wind-element Zanpakutō in Soul Society and has the ability to create gusts, change the wind currents, and even stop the wind. It is said that Okaze can “fan fire, move oceans, and split mountains”. Rei has struggled mastering control of Okaze's Bankai and understands that she needs to be stronger to fully control it. The difference between Shikai and Bankai is the destructive force. Rei compares the two by stating that Shikai is for precision and Bankai is for total destruction.
 * Shikai: Okaze's release command is "Whisper through the Valley". In its Shikai, wind wraps around the blade and leaves black, intricate spirals on it.

wind quickly surrounds Rei’s body. Rei’s appearance is altered when the winds dissipate. Her hair turns light grey and her eyes are golden. The spirals on Okaze are transferred to Rei covering her hands to her elbows. The design on the blade fades significantly. These are normally unnoticeable due to the wraps Rei wears around her hands and lower arms.
