In Karakura Town, there has been a sudden outbreak of unidentifiable spirits called "blanks" (vacant souls) while in the skies of Soul Society, the real world has been reflected. A mysterious female shinigami called Senna has appeared before Ichigo along with a man named Ganryu, leading a group called the "Dark Ones."

"Hell" is the place where a person is sent to who committed violent crimes when they were alive. Shinigami are forbidden to go there. One day, prisoners revolt and make their escape to Karakura—the real world—where Ichigo and his friends live in. Ichigo and his friends are defeated one after the other by prisoners with overwhelming power. A mysterious man appears who comes to their rescue. With Kokutou leading the way, Ichigo, Rukia, Uryuu, and Renji marche into Hell to save the world. Note: Episode 299 of Bleach serves as a prologue to this movie.

After a mysterious pair attack Rukia Kuchiki and erase her memories while she is in Seireitei, Ichigo Kurosaki, a substitute Soul Reaper, briefly forgets Rukia, until he is reminded of her by Kon, an Underpod Mod-Soul. Confused, he seeks his town's candy-shop owner, Kisuke Urahara, who opens the pathway to Seireitei for them. Ichigo is then shocked to find that his allies in Seireitei, the Shinigami of the Soul Society, have forgotten him. Filled with action, Kimi no Na wo Yobu follows Ichigo and Kon as they fight against their former comrades while searching for the missing Rukia and discovering her assailants before they strike again.

Assigned to protect a royal procession transporting a powerful artifact called the "Ouin," Squad 10 gathers in the human world as Captain Toushirou Hitsugaya and Lieutenant Rangiku Matsumoto observe the area cautiously. However, the caravan is suddenly struck by a group of assailants who wreak havoc on the procession, stealing the Ouin in the process. After a brief clash with one of the attackers, the distraught Hitsugaya pursues the escaping thieves, leaving behind Matsumoto and the disoriented squad. Following the incident, the Seireitei brands Hitsugaya a traitor for abandoning his post and puts Squad 10 on indefinite lockdown. In the human world, Ichigo Kurosaki is investigating a spiritual abnormality when he stumbles across the injured Captain, but is caught off guard when Hitsugaya suddenly flees. Soon learning of the situation, Ichigo, Rukia Kuchiki, Renji Abarai, and Matsumoto set off to prove Hitsugaya's innocence and uncover the truth behind the theft of the Ouin. Meanwhile, a ghost from Hitsugaya's past haunts his thoughts as he chases down the true culprit.
