What is kamidere supposed to be?

Nothing. “Acts like a goddess” is vague enough to be meaningless.

H-Ero, if you need food, you're always welcome here

But you’re leaving. That’s just mean.

I met a lady in the meads,
Full beautiful – a faery's child,
Her hair was long, her foot was light,
And her eyes were wild.

I made a garland for her head,
And bracelets too, and fragrant zone;
She looked at me as she did love,
And made sweet moan.

I set her on my pacing steed,
And nothing else saw all day long,
For sidelong would she bend, and sing
A faery's song.

She found me roots of relish sweet,
And honey wild, and manna-dew,
And sure in language strange she said -
'I love thee true'.

She took me to her elfin grot,
And there she wept and sighed full sore,
And there I shut her wild wild eyes
With kisses four.
