Sudden switch in WaniKani Font

[d-hermit]

I think I had the same issue.
Solution in this topic:

The fonts became too bold and illegible

If you do decide to use Jitai, make sure you download additional fonts (or else it’ll only randomize a few fonts). I personally like these: “EPSON 行書体Ｍ” “EPSON 正楷書体Ｍ” “EPSON 教科書体Ｍ” “nagayama_kai” You also have to edit the Jitai script to add the ones you want to use.
