- 80% Chance to Debuff target for -1 ATK/AGI each turn for 3 turns.
- 100% Chance to self-apply Sustained Buff effect that grants +1 DEF every turn for 3 turns.
- Sustained Buff effect also applies a Status Immunity Shield to any ally that does not have an active Shield or is NOT inflicted with a Status Effect.
Shiranui is an interesting Sustain card with quite a few gimmicks. The first is that Shiranui attempts to apply his Sustained Debuff effect on all enemies. If it hits, then you have an 80% chance per turn to reduce your foes' ATK/AGI by 1 each turn for 3 turns. But then Shiranui also applies a Sustained Buff effect to yourself that grants +1 DEF every turn for 3 turns.
The interesting effect of the Sustained Buff is that applies a Status Immunity Shield to any ally that does not have an active Shield or is NOT inflicted with a Status Effect. In short, this makes him pretty similar to Star in that both can protect allies from Status Effects and Debuffs. Of course, much like Star, it's limited in that it won't apply the Shield to any Party member already suffering from a Status Effect, but also has the curious effect of not applying the Shield if Party member already has a Shield on. (This can be good or bad depending on the Shield they have; at best, it doesn't overwrite a more useful Shield.) That said, like Star, Shiranui requires a little bit of planning to get the most out of him, but he's pretty good.
Similar to Fool, Shiranui is a powerful Debuff Sub that starts off quite strong and gets even more powerful as more Turns pass.
Shiranui grants a 25% Skill Boost to any Debuff Card, but after 5 Turns, the Skill Boost increases to 30% and after 10 Turns, it increases further to 35%.
Needless to say, Shiranui is an incredibly powerful Sub for any Debuff card!
Shiranui is a atmospheric ghost light told about in Kyushu. They are said to appear on days of the noon moon such the kaijitsu (29th or 30th day) of the seventh month of the lunisolar calendary when the wind is weak, in the Yatsushiro Sea and the Ariake Sea. Furthermore, they can be seen in modern times, but they have been determined to be an atmospheric optical phenomena.
