Show by Rock!!

Show by Rock!! was a mobile game, combining elements from both rhythm games and raising sim games. Players could choose from 26 different bands, each having their own music style and uses special cards for each gameplay. The player's team could have up to five cards, and choose one support player from a list. The player had a certain amount of "soul" for each element depending on their cards. The player could play whichever song they would like from the band of their choice, as well as the level that works with their team. Occasionally, a band's members' Melodisian Stones may turn dark, and thus a boss battle appears. For the boss battles, you may only choose a song from the band whose Melodsian Stones turned dark, and the goal for each boss battle is to survive until the end. Players also get to create their own character at the start of the game, and design their own room.

Gameplay for Fes A Live was similar to that to the original series that preceded it, but presented it in a landscape format similar to The Idolmaster and BanG Dream!. Unlike the previous game, the game only had a limited amount of bands presented but each are assigned to their musical alignment: Melody, Harmony and Rhythm instead of the traditional elemental attributes of the previous game. Gameplay for the live section mode had the same elements from the original and inherits newer twists such as swipeable notes, the ability to adjust scrolling speed and a more traditional 5-note layout.

A new feature of the game was the town of GURF, which serves as a main hub for the player. Players had to customize with specific buildings in order to gain sound dollars, the game's free currency. These could also be earned by obtaining items after each play session specific to each band, which could be sold to the shop ans also could level up each band. As the player levels up, newer slots in the town were added in order to add more buildings. Also, players could also upgrade buildings by buying them through the in-game store using sound dollars as well. The game also had a boss battle mode, which could be accessed through by finding a corrupted myummon in town and defeating it could earn players with more currency. The game's bromide system also returns, allowing players to obtain bromide cards through gacha using Melodisian Stones and each card could be evolved if certain levels are reached, each having various rarity. In addition to a story mode, the game also had a 69 Memorial Mode, which allows players to read the storyline of the original anime series for new players of the game.

Cyan Hijirikawa is a first-year high school student who has a good passion for music. However, she is very shy and doesn't have the courage to join the school's music club. But on one fateful night, she gets sucked into the rhythm game she had been playing on her smartphone after receiving an item called "Strawberry Heart". Cyan ends up in a new world called Midi City, a place where those who command music control everything. There, she sees a concert performed by a kemono band called Trichronika and realizes she had taken on the form of a white kemono cat girl, dressed in a costume resembling Gothic Lolita fashion. However, when a "dark monster" starts to attack the concert and begins to corrupt the Melodisian stones of the Trichronika members, Strawberry Heart materializes in Cyan's hands and tells her to play something with it to defeat the monster. As she saves the band from turning into dark monsters themselves, she returns to her human form, but retaining her cat ears and tail. She is then approached by Maple Arisugawa, the CEO of Banded Rocking Records to join his recording agency. She meets ChuChu, Retoree, and Moa, the guitarist, bassist, and drummer of Plasmagica, one of Banded Rocking Record's bands. Retoree asks Cyan to join, and she accepts. Together, they all tackle and perform together in the music scene, aiming to be the best music band of all Midi City, discovering the secrets surrounding the Dark Monsters and importantly for Cyan, to find a way to get back to her own world.

Set after the events of the first season, the intergalactic fleet led by the malevolent Queen of Darkness, Victorious, unleashed a devastating attack on Sound Planet in the future, causing total destruction of Midi City. Upon its destruction, a mysterious band named Bud Virgin Logic appeared and performed a malevolent tune to the surviving denizens while Dagger Morse corrupts all the citizens, draining them of their sound energy and plunging the city into chaos and despair. From the attack, only Ninjinriot survived and feared the worst scenario that would lead to the fall of the Sound Universe. With no choice, the band traveled back in time to prevent it from happening. In present-day Midi City, Maple told the members of Plasmagica, Shingan Crimson, and Criticrista that their recording label is holding a beneficiary concert to the people with somewhat positive reactions. Though at the time of the concert, Plasmagica, despite not having Cyan is eager to perform, until Bud Virgin Logic appeared alongside Dagger Morse, who announced he will destroy the ones who defeated them. But they were thwarted by Ninjinriot, who rescued the trio. After Dagger and his band retreated, Arashi told them that bad things will happen if they don't stop Dagger and Bud Virgin Logic, resulting in the said bad future and got everyone worried that there will be a new battle. At the same time in the Human World, Cyan Hijirikawa was stuck in a writer's block regarding composing a song for her band in the upcoming school festival. Kamui arrived at the Human World and transported Cyan back to the Sound World in order to prevent the dark future from happening. With the entire world in a knife's edge, it's up to Cyan and her friends once again to stop Dagger and Victorious from destroying the Sound Universe.

Taking place somewhere after the second season, the story focuses on Howan, a Fox Myummon who lives in the countryside on Sound Planet. Though she enjoys her peaceful life in the countryside, Howan dreams of music stardom and gets the chance to achieve her dream when she passes the audition for a music competition in Midi City. Meanwhile, the guitarist Mashima Himeko is equally passionate about music but feels uncomfortable having been placed in a band with two other young artists, the bassist Delmin and the drummer Ruhuyu. Howan loses her audition pass, making her unable to join the audition. Under the glittering lights of Midi City, when Howan is distraught at losing her audition pass, Howan, Himeko, Delmin and Ruhuyu meet each other for the first time and discover together with what they could never reach alone.
