Just finished my first manga tankouban that didn’t have furigana. It was a bit of a struggle. Book 9 of March comes in like a lion. I actually bought it at least 18 months ago and after getting part way through gave up when I put WK on vacation mode.
Recently I’ve been going back over all the kanji I’ve supposedly learnt (and have been learning kanji in subsequent lessons). Went back to the manga a couple of weeks ago and have managed to get through it.
Got a good sense of achievement and also finally moved onto new material (I’ve watched both series of the anime, which goes up to around half way through book nine). I bought all the books published (back in 2019) as I didn’t want to wait for a series 3 to find out what happens.
