Terror from the Deep!
Activate this Skill during your Main Phase, while you control "Kairyu-Shin". When this Skill is activated, you can activate "Umi" directly from your hand, Deck or GY. While you control "Kairyu-Shin", all WATER monsters you control are unaffected by Trap effects. If "Kairyu-Shin" you control leaves the field, draw 2 cards, and if you do, flip this card over.
