my avatar says it all

okay so i have googled this mutable time but it never tells me anything so i need help, so we all know Titan's bride right,well i was reading ch 31 and it just popped "how old is Caius?" and so i went to the past ch's and looked around i didn't see anything. so can someone please tell me his age because i am literally going crazy over here. also thanks if you help me (づ￣ ³￣)づ
