The facts about the battle of mount fuji are wrong. 1st guren isn't challenged by lancelot, its the other way around.
And second, it says that they ran out of energy to power the wing systems, but they actually ripped off each others wing systems. There isn't really any indication of their low power until they had already been fighting on the Damocles for several minutes.
also, what gives us any indication Rakshata got it back? Kallen was still wearing the key at the end. It was probably put in storage or is still in Kallen's possesion. In either case, maybe we should just end the discussion at the end of the article
