Appearance: A beautiful girl with waist-length orange-brown hair, eyes a darker shade of brown than her hair, and a glamorous physique. Personality: She is airheaded and eccentric, with a way of thinking that transcends common sense. For instance, when asked to draw a picture on the theme of her 'future self,' she drew herself becoming a 'super robot.' Abilities: She uses techniques involving the Shun Shun Rikka, six spirits housed in the hairpins given to her by her older brother, Sora Inoue. These are activated through her heart and the incantation "I reject." The power of the Shun Shun Rikka is the 'rejection of phenomena.' By 'rejecting' various events, she can undo what has happened. As a reality-warping ability that goes beyond simple time reversal, this rejection can even revive those who have been partially erased. However, while she is an incredible healer, her offensive power is poor, and for a long time, she remained the weakest combatant in the party. When she fired Tsubaki, her only offensive option, at Yammy before his release, he blocked it easily and mocked her, asking if it was a 'fly.' Consequently, her offensive abilities fade into the background as the story progresses, and she mostly utilizes her healing and defensive powers.

Ichigo Kurosaki became a Soul Reaper after receiving powers from Rukia Kuchiki. Although his powers were initially stripped by Byakuya Kuchiki, he regained them with Urahara's help, obtained his own Zanpakuto, and primarily fights using swordsmanship. As a child, he was a crybaby and a mama's boy, but his personality changed drastically due to the shock and guilt he felt after his mother, Masaki Kurosaki, was killed while protecting him from the Hollow Grand Fisher. Because of this experience, he holds his family and friends very dear and is willing to risk his life to protect them. He cares deeply for his comrades. While Ichigo falls into the category of a hot-blooded protagonist, he is relatively cool-headed and mature compared to other shonen protagonists. His Zanpakuto is Zangetsu, and his Bankai is Tensa Zangetsu. While the previous Tensa Zangetsu took the form of a long, slender katana with a manji-shaped guard, the current Tensa Zangetsu resembles a massive kitchen knife, much like his Shikai from the first arc. In fact, if the white outer edge of the blade breaks, a sword identical to his pre-awakening Shikai is revealed. While the blade remains a cleaver shape like the old Zangetsu, the handle differs from the original bandage-wrapped design, featuring a proper hilt similar to the zanbatou-style Zangetsu from his Fullbring fusion.

The progenitor of the Quincy and the Emperor of the Wandenreich, a massive organization of Quincy. He is the oldest Quincy, at least 1,200 years old, and the ancestor of all Quincy. He is characterized by wearing a black cloak, a color that contrasts with the typical white of the Quincy. He keeps the Sternritter, an elite force of Quincy, as his direct subordinates. He is a cold-blooded and cruel individual who shows no mercy, killing not only Arrancars but even his own direct subordinates, the Sternritter, once they are no longer useful. His Schrift is "A," The Almighty. He can see all futures, and when activated, multiple pupils appear in his eyes. Yhwach calls these eyes the "mark of a true Quincy." He can know everything he sees, and he can steal or grant the "powers" he has perceived. There is no room for "understanding" or "countermeasures" to interfere. Once The Almighty is fully unleashed, Yhwach can see everything across the distant future, and every power he sees and knows through The Almighty becomes his ally, making it impossible to even wound him.
