If あなた had to wright an essay on why あなた want もっと見る マンガ in your school としょうかん, ライブラリ

I guess some reasons would be that マンガ have japanese traditions in it, which will teach people about japanese cultures and stuff.
Also they would be popular, which would encourage people to read もっと見る books.

Yeah, pretty much just exaggerate your points.. haha. ^_^
