both eyes closed,a buzzing noise,people screaming that's all they could see and hear Kaito and Kentaro could only see and hear this. they tried opening their eyes but they couldn't it was as if a magical current was closing their eyes for them.Kaito and Kentaro both needed their elements to become stronger when they're weak, there was a small pond near where Kaito meditated so he knew about it, he was able to get his strength back by absorbing a bit of the water he was then able to open his eyes. but on the other hand Kentaro needed lighning or thunder to boost up again which he could have produced but there were too many people around so one bolt of lightning could have killed atleast a dozen of them so he could not have risked their lifes. When Kaito opened his eyes he spotted five others with power surge eyes, he ran towards them and took them to the side and asked them all the same question he asked Kentaro,they all knew that Kaito was one of them because of his eyes and because they were like him they were able to see the water flow into his body, thus they trusted him, Kaito asked for their help to try to heal
Kentaro, Asahi being able to control air lifted Kentaro and took him away took him with the group into the depths of the forest there she laid him on his back and told him summon lightning to his body to heal as there were no people around and all the people who saw Asahi carrying Kentaro just saw a group of imaginary people carry him so that none of their powers were revealed. Kentaro summoned the lightning and healed himself to be able to get up and talk about everything
the reason to big energy blast was that water and lightning had collided due to them not being able to control their energy near each other. After that incident the seven of them went to Kaito's house because his mother knew about his water controlling ability, so they went over to Kaito's house to talk and explain about each of their powers.
