Transcendence, Nirvana. Rein had first tried to give a basic meaning to them but it didn't just fit, one thing transcendence and nirvana did for a human was to sharpen their senses beyond limit, allow them be able to see flows they shouldn't normally be able to see, therefore enabling them to do stuff they normally should not be able to to do, like the shunpo skill which allows you to walk while ignoring the interference of space, that is with one step, a transcendent had walked miles or even kilometers, these realms opened a world with endless impossibility and breaching of concepts and laws to those who are worthy.
Rein's eye widened as he saw the vice principal open the door of his transcendent realm.
'I was wrong...it's not just about the senses...' Rein realized his baseless assumptions were wrong. He gulped.
