Hualālai (フアラライ山, Fuararai-san) is an active volcano on Hawaiʻi. Its peak stands 8,271 feet (2,521 m) above sea level, and is estimated to have risen above sea level about 300,000 years ago. Despite maintaining a very low level of activity since its last eruption in 1801, Hualālai is still considered active. Its slopes are covered in lava tubes, tunnels formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. These lava tubes leave caves when the lava in the tube empties.
Although the area receives practically no rain and there is no water source nearby, Charming Man witnessed the tubes being welled up with water at one point. The Lava Rock fragments fall out from those tubes. Charming Man's brother Mauka disappeared there, somehow falling into a lava tube and being dragged away both by the water current and a mysterious person.
The Hawaii State Land Registry Office (ハワイ州土地登記所, Hawai-shū Tochi Tōkijo) holds physical and digital records of all of the deeds of ownership of land in the state, such as those belonging to the HOWLER Company. The security in the office is notable, due to the sheer worth of the documents archived within. For instance, visitors may look at but not touch any of the original documents when consulting them, and a security guard will put gloves on and flip pages for the visitors instead.

Jodio and the others use the opportunity to have the Hualalai slope, in possession of HOWLER Company, get seized by the government. As they enter the MRI section of the hospital, Bobby Jean and Lulu find them there and attack them.
