If a face-up "Fire King" monster you control is destroyed by a card effect (except during the Damage Step): You can Special Summon this card from your hand. If this card is destroyed and sent to the Graveyard: You can destroy 1 card in your hand or that you control. You can only use this effect of "Fire King Avatar Yaksha" once per turn.

By using Fire King Island's effect, you can destroy Fire King Avatar Kirin on the field to get Fire King Avatar Yaksha from your deck. By doing that, you can use Fire King Avatar Yaksha's effect which is to Special Summon it from your hand. It's basically replacing a weaker monster with a better one.
