The "child" starts gnawing on Tsukiko's head.
The girl tries to react quickly, protecting her head with her hand.
-- It hurts, what are you doing?
"What a strange kind of yokai?" Tsukiko thought, while also trying to understand her feelings, how deeply the creature had bitten into her and whether there were any consequences other than pain and bleeding. If she hadn't tried to instill kindness in her heart, she would have considered this an attack.
The guys should come closer, so that, if anything, they can intervene immediately. They can see everything...
/So, that's the bad ending where Tsukiko's (non-existent) brain is eaten out.../
