Forbidden Siren Wiki

The Homuranagi (焔薙) is the family sword of the Kajiro family.

It was created in order to protect Hanuda and its mysterious cult from the religious prosecution during the Tokugawa Shogunate (1603-1868). Once the Homuranagi acquires the power of the Kiruden (木る伝) it gains the power to permanently kill the shibito, like the Uryen.

Jun Kajiro uses the Homuranagi against Kyoya Suda in the inferno, and after defeating him, Kyoya uses it to decapitate Datatsushi. Then Kyoya will keep the sword and use it to exterminate the shibito.

Etymology of the Name[]

  • 焔 Homura = (noun) Blaze / Flame, (adjective) Glowing / Blazing.
  • 薙 Nagi = (verb) To weed / To shave (薙ぐ nagu).

Homura·nagi can both mean:

  • Weeder of blazes. (As stated in Item 96; If considering (焔) as a noun).
  • Blazing weeder. (As seen by the flaming sword that Kyoya wields; If considering (焔) as an adjective).


  • Item 84; Tamon Takeuchi's notes

    In Forbidden Siren 2 you must break 4 seals as well, but while in Forbidden Siren 2 the seals release the dark, in forbidden siren through breaking the seals a protective force is released instead.
  • Tamon Takeuchi realizes that there must be a contrary force to Datatsushi.
