Second season of B-Project: Kodou*Ambitious.

Mirai Kuriyama is the sole survivor of a clan of Spirit World warriors with the power to employ their blood as weapons. As such, Mirai is tasked with hunting down and killing "youmu"—creatures said to be the manifestation of negative human emotions. One day, while deep in thought on the school roof, Mirai comes across Akihito Kanbara, a rare half-breed of youmu in human form. In a panicked state, she plunges her blood saber into him only to realize that he's an immortal being. From then on, the two form an impromptu friendship that revolves around Mirai constantly trying to kill Akihito, in an effort to boost her own wavering confidence as a Spirit World warrior. Eventually, Akihito also manages to convince her to join the Literary Club, which houses two other powerful Spirit World warriors, Hiroomi and Mitsuki Nase. As the group's bond strengthens, however, so does the tenacity of the youmu around them. Their misadventures will soon turn into a fight for survival as the inevitable release of the most powerful youmu, Beyond the Boundary, approaches. [Written by MAL Rewrite]

Kasumi Toyama and the members of Poppin'Party—their high school band—are now second-year students, but with the new school year comes their latest set of challenges: student council duties, cram school, and part-time jobs, among other things. Furthermore, they are now separated into different classes, and as a result, their free time together is shortened. Looking back, their joyful times together seem like nothing more than an unachievable fantasy when their members are too occupied to even gather in Arisa Ichigaya's basement for practice sessions. As the band ponders over the situation, an unfamiliar girl suddenly emerges, unknowingly pulling them into the spotlight once more. In this rising era of girl bands, Afterglow, Pastel*Palettes, Roselia, and Hello, Happy World! begin to make their appearance as well. Each band, comprised of musicians with their unique personalities, illuminates the stage with its performances. As Poppin'Party returns to the music scene and encounters new friends, the sparkling, heart-pounding music starts to play once again! [Written by MAL Rewrite]

On his way to Areishia Spirit Academy, Kamito Kazehaya runs into a naked Claire Rouge, a student who had been bathing as part of a purification ceremony. She had been preparing to form a contract with a powerful spirit in order to acquire more power as an "elementalist." Her efforts are wasted, however, when Kamito ends up with the spirit despite the fact that only shrine maidens can become elementalists. Yet to be discouraged, Claire then announces that Kamito must become her contracted spirit instead! After reaching the school grounds, Kamito escapes from Claire and meets Headmaster Greyworth Ciel Mais, who invites him to enroll at the academy. Although his life at Areishia will be far from easy as the only male student among the shrine princesses-in-training, he begrudgingly accepts in exchange for information about his former contracted spirit, Restia Ashdoll. Adding on to that, he also must fulfill Greyworth's main request: to win in the Blade Dance, a battle festival occurring in two months, where he will face the strongest elementalist rumored to be contracted with a darkness spirit.
