"In what sense?" Ryuk asked with curiosity.
"I can see your cup too. But there's a problem." Isha said as she narrowed her eyes at Ryuk's heart, her gaze filled with confusion.
"When I look into your cup...I can't see its end. You don't understand."
"Others' cups can be easily seen. I can even see the liquid inside, peering straight through and gauging everything at a glance. But you..." She frowned.
"Even when I look directly down at your cup, I can't see its depth. It's incredibly deep. Really, really deep."
"Because it's so deep, I have no idea how much liquid you have inside. That means I have no clue how strong you really are."
"That was why I didn't help out in the battle with the Colossal. I was hoping it would force you to reveal your strength, so I could finally gauge whether that liquid inside your cup is plenty or barely a drop."
Isha's explanation made Ryuk furrow his brows.
