Mushihimesama

A version for Microsoft Windows was also published by Degica in 2015. In 2021, the game was ported to the Nintendo Switch. The game has an insect theme as all of the enemies resemble various insects such as beetles, like the Japanese rhinoceros beetle and butterflies. The game is set in various forest environments. It received a sequel in 2006, known as Mushihimesama Futari, and a spin-off iOS and Android game entitled Mushihimesama Bug Panic.

The world of Mushihimesama is a wild, untainted one where large desertic areas abruptly change into lush forests, all inhabited by arthropods called Koujuu: such beasts (basically oversized insects) are capable of surviving due to their hardened shells and, upon their deaths, leave them behind for vegetation to grow around them, in a natural cycle of life and death. However, their life force, called Levi-Sense, proved to be poisonous to humans to the point of being named the Miasma; only sparse human settlements were allowed to survive, one of them being the Hoshifuri village, in exchange for the sacrifice of a 15-year-old girl every 200 years. However, the daughter of the royal family, Reco, is apparently the next in line after being given an ornate bracelet by a mysterious boy in Shinju Forest, where she lost herself at a young age: by the day she turns 15, the Miasma contaminates the village. In order to save her people, she enters Shinju Forest once more, riding the golden Koujuu beetle Kiniro (with which the golden bracelet grants a telepathic link) on a quest to meet the Koujuu god himself.

Taito released a PlayStation 2 port in Japan in 2005. A limited version also includes young Reco and Kiniro figures. Exclusive to this port is Arrange mode, a variation of Maniac mode where the player starts out with much more firepower but no continues. Also, if the player makes contact with a bullet or an enemy while holding at least one bomb, the player does not die and releases a bomb instead. The player can also cycle through all three weapon types by pressing a button.

Cave ported Mushihimesama to iOS platforms under the title Bug Princess, which was released on December 15, 2011. "Hell" difficulty features equivalent bullet patterns to the arcade release.

Cave released an HD version for the Xbox 360 on May 24, 2012 in Japan. The game features Novice, Arrange and Xbox 360 modes. Arrange is a modified version of the PS2 Arrange mode; while no Arcade mode is included, the Xbox 360 mode is identical to the arcade release bar HD visuals. First print copies included Version 1.5 as free DLC. The game was released in both regular and limited editions with different cover art. The limited edition included an arranged soundtrack CD.

Degica released a port for Microsoft Windows through the Steam digital distribution platform on November 5, 2015. This release, developed chiefly by Cave, is based on the Xbox 360 "HD" port, and includes the same Novice, Original, and Arrange modes rendered with HD graphics. Unlike the Xbox 360 version, however, where Version 1.5 mode and the arranged soundtrack were only available in limited quantities, the Steam version offers these as paid DLC available to all. Additionally, whereas the Xbox 360 port was region-locked to NTSC-J hardware, the Steam version is an international release with no region restrictions.

An HD version of the game for the Nintendo Switch was released on the Nintendo eShop on June 15, 2021. It includes Novice, Original, Arrange, and Version 1.5 modes as standard features. The game would later be delisted on August 10th, 2024 due to the game license expiring.
