It's just as I said--a test of skill.

[Jack dramatically points at Yuya with the candle.] Mine as a demon, and your's as an ESPer!

[He sets the candle down again.] These are the rules. We'll have to find something more suitable than vases and candles, but I'll throw something at you, and you catch it with your telekinesis and throw them back at me. If you hit me, you win. If you drop anything, you lose! Understand?
