Spirit in underground cave.

Amidst the training, where Kenta continues to use the Lightning Flicker, to overwhelm his own senses and energies to their peak capacity.

Kenta was also starting to train his swordsmanship to put more strain on his body. Which was resulting in the breaking down of the very foundation of his body, making him feel like to go through the burning nirvana itself.

After half an hour of practice, Kenta's body was practically numb to the effect of the full-powered Lightning Flicker, so he lessens the amount of mana and continued to release Lightning Ficker.

"Kenta! So here you are..." Aria came to search for him, who was drowning inside the river while using Lightning Flicker. Due to this, the amount of cold he was able to feel on the skin of twice colder than normal. Which flicked his senses off and he was unable to hear anything out of the river which included Aria's voice.
