Toyama Kasumi is the main protagonist of the BanG Dream! franchise. She is a second year student at Hanasakigawa Girls' High School and the leader, vocalist, rhythm guitarist, and songwriter for Poppin'Party. Outside of the band, she is friends with Aya and Yukina, and, alongside Arisa, is also classmates with Misaki. Kasumi lives with her parents and has a younger sister, Asuka - whom she calls "Aa-chan" - however, it's not always clear who is the more responsible out of the two. __Appearance__ Kasumi has purple eyes and brown hair worn loose with segments pulled up into star-shaped buns. Her short bangs are framed by longer forelocks held by red star-shaped clips. In her initial casual wear, she wears a long blue button-up t-shirt dress accompanied by a yellow flannel tied along her waist. She also pairs it with a silver star necklace and a black watch. __Personality__ Cheerful and high-spirited, Kasumi is a playful, active, and generally positive girl that always finds something to be excited or passionate about. She easily makes friends and gets along with everyone, regardless of their personality. She, alongside with Tomoe, are capable of sharing a mental wavelength with Kokoro. She is also the type to believe in (or fall for) the strangest explanations. However, Kasumi is also quite forgetful, tending to do important things by last moment (though unintentionally so.) She loves to tease Arisa, but given her kind personality, it's hard to tell if she is deliberately trying to provoke her or if she's oblivious. At times she can also behave melodramatically.

BanG Dream!
When Kasumi Toyama was out camping as a child, she heard the rhythm of the "Star Beat" while admiring the starry night sky. This sparkling, heart-pounding sound left a lasting impression on her, and since then, she has constantly been seeking to rediscover that exciting thrill. Now, as a newly enrolled student of Hanasakigawa Girls' High School, Kasumi is more determined than ever to find that long-lost sensation again. She attempts a myriad of school club activities, and even considers taking up a part-time job, but none of these feel suitable for her. That is, until she chances upon a star-shaped guitar in the storage room of an old pawn shop. It leads her to a live house, where she is captivated by watching a live performance for the first time. Spurred from the adrenaline, she instantly decides to form a band without even really knowing why. However, such a venture requires her to confront various hurdles with new friends she makes along the way, all in her pursuit to encounter that twinkling, heart-throbbing ardor once more.

BanG Dream! 2nd Season
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!
