I finally mustered up any speck of courage, outweighed by my desire to learn further, to query Yuichi about this so called 'energy' mentioned that reside within people.
"Um... if you don't mind, and if it's possible... can you explain how you just did that?"
Deafening silence sank above our heads and all around. At first, Yuichi appeared slightly confused without moving a muscle as if he was trying to process the current event.
"...I'm not too good with explanations. ...And this doesn't really have any solid phenomenon to it that can help you understand..." He then managed to mutter, close to a whisper.
"Oh... I see..." I looked down, a frown transcending over my mouth.
(I guess I was right after all... There goes my answer.)
