So I'm a Spider, So What? manga volume 10 features story by Okina Baba and art by Asahiro Kakashi.

Mother’s going down! But there’s one teensy-tiny snag in my strategy to take out Mother--that is, we’re both spiders. So Mother’s got a lotta experience with tricky traps and countering them...and now I’m in a pretty pickle. Stuck with no way to counterattack, my last remaining hope is for my fellow Kumokos to return...!!
