Welcome to the fascinating world of Gensokyo, in which youkai (A term for all sorts of spiritual creatures), animals and some humans live, completely separated from our world by a magical barrier. The only gateway between the two worlds is the Hakurei shrine. Reimu Hakurei is the maiden working at said shrine. Whenever problems of supernatural causes (known as "Incidents") occur, Reimu goes out with her friends to investigate, eliminate the cause and hopefully restore Gensokyo to its equilibrium.

Rumor has it that Momo Kawashima, former student council member at Ooarai Girls Academy, is bound to repeat a year. Having failed her university entry exams, she is far from spending another year at Ooarai, but her plight is unenviable nevertheless. The only way for her to gain admission into a university is to be granted an athletic scholarship. With the Winter Continuous Track Cup rapidly approaching, Momo becomes the commander of Ooarai's tankery team, so as to demonstrate her sport skills and wipe away the stain on her honor. Their first opponent—French-themed BC Freedom High School—is split into two factions that are constantly at odds with each other. Despite this seemingly fortuitous match against a disorganized rival, Ooarai might soon find itself taking one step too far. [Written by MAL Rewrite]

As preparations begin for Seisho Music Academy's yearly Seisho Festival, the girls of the 99th class are gearing up to perform their very own rendition of "Starlight," the tragic tale of two goddesses drawn together by the glow of the heavens but destined to be pulled apart, never to meet again. Created to foster the next generation of theatrical talent, this girls’ only school works to improve the singing, acting, and dancing skills of its students. One student is 16-year-old Karen Aijou, an easygoing girl who has dreamed of performing on stage since she was a child. Her love for theater is further invigorated when her childhood friend Hikari Kagura transfers to Seisho Academy. Through her old friend, Karen stumbles upon a secret elevator leading to a massive theater underneath the school. Hosted by a talking giraffe, this arena serves as a battleground where her classmates participate in duels to determine who among them deserves the title of "Top Star," earning them the right to play one of the lead roles in "Starlight." Emboldened by the promise she made with Hikari to someday be stars together, Karen enters these mysterious battles in the hopes of making their dream a reality.
