I know we have a wide variety of skilled learners in this thread so give this a read if you want some practice, some mining, and of course some really, really spicy delusional PekoMiko fan-fiction.
https://www.pixiv.net/novel/show.php?id=14655951It is fairly easily written with not a lot of difficult kanji and the grammar is very basic. The most annoying thing is a lot of the kanji are written as hiragana so it can be pretty messy.
But fuck me was this some good PekoMiko and I got to mine 75 words out of it.
