Yousuke is catching on. He instead casts Garudyne at the shadow, knowing that even if it bounces back, he won't be hurt. It's worth the time it takes to fish for weaknesses.

Naoto, on the other hand... Well, she's painfully aware that while she's quite good at wiping out large numbers of smaller shadows with her instant kill techniques, she's woefully unequipped to deal with larger shadows that have specific weaknesses. She can always attack physically, but that won't work here... And a Megido-level spell would take toll on her stamina.

for now, she backs off, defends, and watches closely for an opening.
