Hiiragi Kashima and Shizusumi "Shizu" Yagi's band "syh" is set to debut, but they run into trouble when their support guitarist leaves. Although Hiiragi often clashes with Ritsuka Uenoyama—the smug boyfriend of his childhood friend Mafuyu Satou—Hiiragi convinces him to perform as their temporary member. Despite their friction, Hiiragi acknowledges Uenoyama's talent and respects his hard work—to the point of asking him to complete an old song that Mafuyu's ex-boyfriend, Yuki Yoshida, left behind. In between writing, recording, and filming a music video, Hiiragi comes to terms with his love for the aloof Shizu and wrestles with how to convey his feelings. Meanwhile, "given"—composed of Uenoyama, Mafuyu, and their bandmates Haruki Nakayama and Akihiko Kaji—receives an offer to debut as well. The members are ready and beyond excited, save for Mafuyu, who has never before thought about playing music professionally. As Uenoyama attempts to understand Yuki and replicate his unique sound, Mafuyu steps back to ponder over the looming changes in his life, fearing what the uncertain future may bring.

Hikaru Amatsuga's days of tranquility come to a sudden end when he rescues Alma, a mechanical arm crying for help. Alma fuses with his jacket, introducing Hikaru to the world of mechanical arms: mysterious, sentient weapons that normally become a part of their users' bodies. Forced to flee for his life, Hikaru is eventually captured by Aki Murasame, a twin mechanical arms user working for ARMS, an organization that protects the machines against unethical treatment. The Kagami Group, a nefarious organization that treats mechanical arms as mere tools, seeks to recover Alma. Hikaru is deemed a failure by ARMS for his lack of natural predisposition to be an mechanical arm wielder, so Aki is assigned to be his bodyguard. But Aki is defeated by Jun Kagami, who cruelly tears out her two mechanical limbs, condemning the girl to a slow death. Unwilling to abandon Aki to her grim fate, Hikaru miraculously awakens his power and neutralizes Kagami. Now a full member of ARMS, Hikaru is determined to unravel the truth about mechanical arms and protect his newfound friends and allies.
