Zakai: *he reaches his hand out and glanced at the boy with levitation and plant manipulation, he rose an eyebrow and opens the palm his hand which sets a  large wave of ice spikes flying to Titus way*

Titus: *he levitates himself up, but his maximum was only 50 feet high and he knows Zakai can aim higher than that*

Aria: *watching the two boys train, despite them barely knowing each other and most likely not going to end up in the same time, she was still impressed by how strong Zakai is*
