Can I sell fanart of some of my favourite Shojo-Anime?

Hey there! Currently I catched myself drawing a lot of fanart of my favourite Shojo Anime: Kimi ni Todoke, You and I are polar Opposites, Shikimori is not just a cutie and Skip and Loafer. I was thinking of creating stickers, pins and Charms of my fanart, but I can't find anything regarding the IP and if it's even allowed to sell fanart of those anime in small batches (I don't have an online shop, so it's convention exclusive).

Does anyone have any experiences regarding this? Thanks!
