And, how it was stated in this thread before, one of Ragna's belts has -NO.5- Es written on it. Es is short for Embryo Storage, and there is also -NO.5- mark on Ragna's neck. If Ragna being an Embryo Storage unit were to be true, then he would have lived for more than a century (Embryo Storage Units appear in the XBlaze game, which takes place in the 2040s, more than a century before BlazBlue does). It would also cause continuity errors as to whether he is actually Jin's and Saya's older brother, unless the person Ragna was based off of cryogenically preserved himself for more than a century to conceive Jin and Saya. Es could also be a shortened version for Epsilon, which is the 5th letter of the Greek Alphabet (the same naming system is used for Murakumo units), and given that he has 5 on his belt, it seems much more likely for him to be a Murakumo Unit than an Embryo Storage Unit.
