All he's ever wanted was somebody to stay by his side like this.
They used to call him by a number. When he lost his memories, he supposedly threw a tantrum whenever they called his real name. So they called him by a number to temporary replace his name. Kazuya recalled his emotions then, 'it's better than that name. I don't want to remember anymore.' The next day after receiving his new number day name. He completely forgot his real name; all that remained was a numb and hollow feeling in his heart. He controls his powers within the following week.
People showed him with endless flattery and called him a genius. Kazuya didn't care about it, perhaps because he didn't understand it well. Who cares whether he can control his powers so easily? Is it that rare of a case? Deep down perhaps he was thinking, 'aren't there other people out there like me?' Back then he already displayed signs of a child who wanted attention. A lonely child, but he didn't realize it.
