Is there an option to search multiple tags?

Yes

click menu, or the three lines on the top of the page, then press “all genres” and then you can click once on tags you want and click two times for tags you don’t want!

how?

I know that option but thank you.
When you open one manga and go down you see tags and all the tags that people tag, I'm talking about those
But thanks (=・ω・=)

oh mbb
