Shinwonryu is a Shinsoo manipulation style which can only be mastered by "Those who have opened the door" (most likely the Irregulars).[1][2]

This technique compresses Shinsoo around onto a single point and releases it as a huge explosion. According to the "God" of guardians, this technique is far above what ordinary Regulars can hope to achieve; a small amount of Shinsoo can cause great destruction.[2] A tired Baam, using a single baang of this technique on a pack of big Crystal Shards, was able to utterly annihilate all of them in an instant[3] lending credence to the sheer power of the technique.

Notes and Trivia

  • Baam found this control skill fundamentally foreign in comparison to everything else he had ever learnt, needing two months to learn it despite it being used on him.[2]
  • The "God" of guardians can only use this technique in the Hell Express.[2]
  • It is likely the true name of this technique will remain hidden until SIU reveals the corresponding hanja.[4]
  • SIU based the visual on "light" rather than "water" for shinsoo.[5]
  • The technique has been shown to be able to surpass the spell endowing immortality to 43rd Floor inhabitants.[6][7] This has been assumed by the fandom to be a result of the way the shinsoo is controlled.
