The Fire Moth was an organization of the Old World that has been wiped out prior to the current civilization. Its purpose was to serve and protect the last of Humanity but failed and was wiped out by the final (14th) Herrscher of the era.


The Fire Moth (long name: THE MOTH WHO CH△SE THE FL△MES)  was a rebel organization located in Nagazora City, which was founded by human beings in the Old World. The mission of this organization was to protect people and eliminate Houkai threats.

However, when the 14th Herrscher destroyed the Old World, this organization was also wiped out.

Acronym: MOTH (Myrmidon Of Taskforce Houkai)



Quantum Mechanics

Professor Mei researched quantum mechanics and used its capabilities to eliminate Houkai threats.

Sacred Relics

Sacred Relics are a series of mass-produced weapons driven by materials similar to the Herrscher core, with a unified design style. In Schicksal organization, many Sacred Relic weapons have been unearthed in many places such as Baikal. The holy relic weapons currently available in Houkai 3rd are as follows:

  • 2nd, light long-range general-purpose combat weapon (Double Pistols), excavated on Lake Baikal
  • 3rd, melee combat adaptive combat weapon (Sword), excavated on Lake Baikal
  • 5th, ultra long-range special combat weapons (Missile), excavated on Lake Baikal
  • 7th, general-purpose slash weapon (Claymore), excavated in the Black Forest region of Germany
  • 11th, general-purpose weapon (Cross), excavated in Hardanger, Norway

Soldier Project

When the organization discovered that the 7th Herscherr was too strong against any normal human, Professor Mei started the Soldier project in order to improve human strength by fusing the human body with the DNA of Houkai beasts. These soldier were called "Fusion Warriors" or MANTIS (Massively Augmented Neo-Tech Integrated Soldier)

  • Kevin Kaslana was later fused with the DNA of the Emperor-class Houkai beast, Parvati, giving him the power to control ice, and also make his body temperature drop to -30°C, making anybody standing near him turn cold. With his newfound ice powers, he used Judgement of Shamash to defeat the 7th, 9th and 11th Herrscher.
  • In order to maximize the effects of the experiment, Dr. Mei decided to gather surviving soldiers on the battlefield and throw them into a ruined city full of Houkai beasts. Wanting to use life and death to stimulate the potential of the subject's body, and improve the success chance of the Fusion Warrior experiment. A new super soldier was born: MSA-209 HUA.
  • In Sea of Quanta, there is a Fire Moth super soldier, numbered CM-004. Appearance is same as Unforgotten Apostle, with a pendant storing electronic photos of herself and her sister on her neck.

Holy Sword Durandal

Currently only appears in visual novels.

According to its own description, it is a super weapon built by the pre-civilization era. The author personally speculates that it was an experimental weapon that the pre-civilization tried to achieve the same destructive effect as the God Key without using the core of Herrscher. Although it is also made of Soulium, it differs from the God Key in that it is powered by 7 "gems" with different sub-functions, and can only exert its full power when all 7 gems are attached to the sword. One of the gems is AI with self-awareness. Each gems has its own unique use when it is independent of the sword. The complete weapon can cut the space itself, causing unavoidable damage. After being made, it fell into a sleep state.

The God Key Project

Mei and Prometheus A.I. created this project in order to make God Key weapons, and use it against Houkai. Eleven powerful God Keys were made in total before the organization was wiped out. However, only 7 out of 11 God Key weapons were found as of today.

Project: Stigmata

This is the last project created by Professor Mei to implant stigmata to the human body.
