Moriko is a 30-year-old shut-in who just gave up her job to become a full-on NEET, and spend the rest of her days locked in an apartment playing MMO games.

"Yep, my name's Lily! What, are you trying to... 'pluck' me?" (think of 'pluck' as her trying to low-key get across an innuendo)
(smug) "You sure you can handle a sword that long?"
