Arc 1The Quincy Invasion
Shuichi joined the First Division, awakened his Zanpakutō, and took part in the campaign against the Quincy. The Quincy launched a devastating invasion of Seireitei, and after Yamamoto confronted Yhwach, Shuichi found the wounded Furoufushi Saito facing another Quincy.
- Shuichi trained under Yamamoto and Sasakibe, graduated as a Soul Reaper, and chose to join the First Division.
- Shuichi discovered Quincy forces in Rukongai, fought their soldiers, and awakened his Zanpakutō, Heaven of the Other Shore.
- Shuichi and his companions destroyed a Quincy fortress and later investigated a Quincy base in Karakura Town, where they encountered Ishida.
- Ichibē Hyōsube warned Yamamoto that Yhwach was coming, while Shuichi learned that the hazy figure in his Inner World was his Zanpakutō.
- Yhwach’s forces invaded Seireitei, and captains and noble clans fought Sternritter across the city as Shuichi remained in Sword Meditation.
- Yamamoto confronted Yhwach with his Bankai, and Chōjirō Sasakibe paralyzed Yhwach long enough for Yamamoto to strike him with Dawn Blade.
- Shuichi awoke amid the devastation and found Furoufushi Saito wounded as a blond Quincy approached, so he attacked with his Zanpakutō.
