In sixth grade, childhood friends Yukiya Asagi and Miku Sakura created a game with the objective to embarrass the other person by taking turns saying I love you. Four years later, even as they are entering high school, the two are still trying to one-up the other and claim victory. However, as tender feelings begin to bloom in their hearts, the simple phrase has taken on new meaning beyond the rules of their game. With the passing of each day, the urge to become more than childhood friends grows—but both Yukiya and Miku resist making the first move, hesitant about what is in store once the game finally ends.

A reunion that was supposed to spell the arrival of peaceful times is quickly shattered when Subaru Natsuki and Emilia return to Irlam village. Witnessing the devastation left behind by the calamities known as Sin Archbishops, Subaru sinks into the depths of despair as his ability to redo proves futile. As the group makes their way to the Sanctuary in search of answers, Subaru has an unexpected encounter with the Witch of Greed—Echidna. Subjected to her untamed rhythm, he is forced to dive into the spirals of the past and future. At the same time, several mysterious threats set their sights on the Sanctuary, heralding a horrific fate for the hapless people trapped within. Everlasting contracts, past sins, and unrequited love will clash and submerge into a river of blood in the second season of Re:Zero kara Hajimeru Isekai Seikatsu. Pushed to the brink of hopelessness, how long will Subaru's resolve to save his loved ones last?

After a stern yet compelling speech by Otto Suwen, Subaru Natsuki solemnly swears that he will successfully make it through this timeline and save everyone he can along the way. The first step toward achieving this goal is to help Emilia work through her past; however, that is easier said than done. Feeling as if she has been lied to by everyone around her, it will be difficult for Emilia to trust anyone, even Subaru, her self-proclaimed knight. Re:Zero kara Hajimeru Isekai Seikatsu 2nd Season Part 2 presents the culmination of Subaru's experiences with the Sanctuary and its people, along with his unwillingness to give up hope on saving them.
