Black Fish is a Shinsoo technique that Scouts use to block out the light of a Lighthouse. This allows the Scout to become "invisible" which is suitable for Scouts as they like darkness. This is used to both hinder the attack of Fishermen and Spear Bearers.
Of course, Light Bearers can use reverse techniques to counteract the blocking spell.
Notes and Trivia
- SIU has a notable love for aquatic life, the name of this technique being one of many examples.
- Black Fish's Korean name, "Heuk-rin", means that like a waving black feather, it blocks out the light.
