Odysseus is now taken, sadly, to those who were interested in summoning him. It's just too perfect a pair for me to let down on.

That being said, some of the servants Hisoka is interested in summoning are Hugues de Payens [@Asuras] , Cao Cao [@Psyker Landshark] , Chi-You [@Holy Grail] , and the possibility of either Casters.
