So I'm a Spider, So What?, Vol. 6 (light Novel)

I-i-it's not like a spider needs friends!

I did it! I'm finally an Arachne!...Aaand things already aren't going the way I thought they would. I'm inexplicably on a road trip with the Demon Lord, a reincarnated baby, and her troubled vampire guardian. I don't really interact with them much, besides subjecting my reborn classmate to insane training, watching the party sneak off into villages, hearing about the delicious food they eat...Wait, hold up. Doesn't it seem like I'm the only one who's being left out?!? W-w-well, the monsters up here taste delicious, so whatever! Sniff, sniff. I wonder if my other brains are having a better time... What are they even up to?
