Ryuk's eyes met Felina's, her darkened gaze returning to her face, despite Felina's flat expression. Several newbies flinched, even the audience tried to run out.
Felina didn't move at all, even though the attack couldn't be stopped by another Sound Wave.
Killian looked away, even after sensing Ryuk's pungent bloodlust. He didn't fault Ryuk's actions as much as he did her reasoning. He understood why later on.
Ryuk's opponent being able to drop Ryuk's guard by calling her name meant that they were friends, just like Jane and Kia who never hit the other when they were down.
But the spiky-haired girl specifically attacked Ryuk's lower area, which was a special area for most Wind users as that's where their mana concentrated.
Only close friends would know about the other, and the girl had to use it against Ryuk because of her fear for Felina.
