In the RP
Max, in Hybrid, summons Riku to discreetly transport Gray across to Edira's place in the woods near Westwind.

Riku goes away after this for unknown reasons.

His next appearance is in Death, Deceit, and Decadence. He appears when Gray was bitten by Wellop, he saves her when Max gives him the sigil stone, for unknown reasons. Riku Yukimura has not appeared since then.

It is possible he will be summoned again.
