About
Kaiju (怪獣, kaijū) are gargantuan beasts that serve as sentries that prevent mortal Souls from entering regions on The Continent meant only for use by Gods and other divine beings.

Similar to Holy Beasts, kaiju are extraordinarily large creatures, with each being roughly the size of a mountain. There is no apparent consistency between their physical appearances, making every individual of the species totally unique from its brethren. Due to being created solely for the purpose of warding off mortal beings, they have incredibly simplistic minds, and do little more than move around their designated territory until a foreign body approaches them. When confronted with an intruder, kaiju will begin attacking relentlessly until the threat is eliminated, demonstrating a ferocious level of tenacity in the process.

As the guardians of the Gods' Realm, kaiju possess power far beyond most other creatures on the Continent, making combat against them all but impossible in most instances. They are naturally capable of damaging the Invincibility Field, rendering even the average Dark Lord helpless in the face of them. Kaiju are also functionally immortal, and will instantaneously return to life only a few short moments after being defeated, meaning that it is impossible to ever truly win against one.

Currently, eight kaiju are known to exist. Of these eight, four are located in far-off reaches of the Continent: UR, who dwells deep underground; Raidboss, who resides in the transient stretch of water known as The Sea; Multibattle, who lurks somewhere within the distant skies; and Gogo, who prowls beneath the River Styx that serves as the passage that transports departed Souls into Hell. The four remaining kaiju each inhabit one of the massive floors along the hidden pathway behind the Gate of the Gods in the Ancient Ruins that leads directly to the domain of the Creator God Ludo-Rathowm. As all of these locations are exceptionally difficult to reach, very few people have ever encountered a kaiju in their lifetime, and even fewer have lived to tell about them.

In Kichikuou Rance, kaiju are supported in battle by organisms known as Dragonflies (トンボ, tonbo). These dragonflies do not receive any kind of dedicated graphics, however, making their appearance and function a mystery. No mention is given to dragonflies during the appearances of either of the kaiju depicted in Rance X: Showdown, making it unclear if they are still considered to exist in canon.

Trivia

 * The three kaiju introduced in Rance X each have names relating to mechanics in smartphone-based gacha games, most directly Granblue Fantasy. According to TADA, the director of the Rance series, this was done to make them evoke the feeling of being "event bosses that everyone wants to beat".
