CrusaderV is Kolosus, just renamed. Kolosus (on his skype) has also told me in the past he was going to rename his name to CrusaderV, also on the Contact Info thread, Sachi surprisingly had the same Skype name. Coincidence? I don't think so. Also, I know Nnaass in real life, he lives pretty near me; apparently what Kolosus (Nnaass) told me, he lives in a compound roughly 3 kilometers away, and goes to a school, again near to mine (and Nnaass' as well). He's apparently also in the same grade as me by coincidence! Either this is the world's largest coincidence ever, or concludes Sachi = Kolosus = CrusaderV = Nnaass = Roronoa_IV.
Also, when I first talked with Sachi about the clan, he acted as if Kolosus/CrusaderV is another person.
