Back in his life as Fruity, Klaus was a mischievous monk. Back then, his mother and Haniva sacrificed themselves to send him away, where he was taken in by a group of monks.
He grew up with them and was very happy around them. He had hundreds of uncle monks to play with.
He called them Uncle Monks because that was what they said he should call them. Though he knew some of them by their names.
His life was good. But while he was close with all the monks, he was closest to one of them.
This one was none other than his Uncle Monk. Of course, he called them Uncle Monk, but this one held a special place in his heart. He had been with him daily while growing up in the monastery.
He practically raised him. This means he was the one who endured Fruity's (Klaus's) mischievousness the most.
