Set several years after the events of TwinBee, players assume the role of Light and Pastel (marking their debut appearance) taking control of TwinBee and WinBee to defeat invading forces of the evil alien Iva and save planet Meru after receiving an SOS message sent by Princess Melora.

The game proved popular among Japanese arcade players, earning several awards from Gamest magazine, while its ports to other platforms were also met with positive response from critics.

[4][5] The title marked the debut of Japanese animator Shūjirō Hamakawa (credited under the pseudonym Shuzilow.Ha) in his first project as game designer, serving as character illustrator for subsequent installments of the TwinBee series.

[4][6][7][8] Konami Kukeiha Club members Hidenori Maezawa, Masae Nakashima and Michiru Yamane scored the soundtrack.

[22][23][24] The PC Engine conversion was re-released for the Wii's Virtual Console as a "Hanabi Festival" launch in Japan on September 18, 2007, then in North America on March 23, 2009, and later in PAL territories on July 24 of the same year.

[31] In addition, the PC Engine version was also re-released in Japan for Windows through D4 Enterprise's Project EGG digital service on March 3 of the same year.

[45] Both Martin Gaksch and Heinrich Lenhardt of German magazine Power Play regarded the game to be a nice vertical-scrolling shooter with enjoyable candy-colored visuals.

[49] This version also proved popular among the X68000 userbase, eventually being nominated for a "Game of the Year" award by Oh!X but losing against other titles such as Parodius Da!.

[54] Both Kaneda Kun and François Hermellin of Consoles + praised the PC Engine conversion for its colorful graphics, sympathetic music and impeccable gameplay but criticized the presentation.

[41] Computer and Video Games's Frank O'Connor commended the PC Engine port for its arcade-accurate presentation and gameplay but criticized the music for being annoying.

[37] Olivier Prézeau of Joypad and Joystick's Jean-Marc Demoly praised the PC Engine port for its graphics, sound and controls as well.

[55][56] Reviewing the Virtual Console re-release, Nintendo Life's Corbie Dillard praised its responsive controls, arcade-accurate visuals and upbeat soundtrack.

[42] Eurogamer's Dan Whitehead compared it with Xevious, stating it was not as good as MUSHA nor as cute as Fantasy Zone but regarded it as an appealing vertical-scrolling shooter for casual players.
