>>24072135It's a really long road with Kanata because of the sheer amount of random Japanese topics she broaches; however, I think you can pick up the grammar and vocab required to understand a lot of what she says about games / during games relatively quickly (and these will transfer between other vtuber/game streams).
If you're going from not understanding anything to understanding game-topics, even that is still worth it I think. You'll likely still be completely lost for a very long time when she brings up a random culture topic in the middle of playing a game, but there's no point worrying about stuff like that. Get the grammar under control and you'll at least be able to identify and (hopefully) spell the unknown subjects or verbs she says so you can at least jisho it if you really want to know what a specific sentence meant.
Though I think learning kanji is fairly crucial to studying unless you just use google lens to cheat, if you do skip kanji you should probably at least do a quick study of radicals. If you put a bit of time in radicals (its a minute fraction of the time required to learn kanji), you can at least go on your phone or on jisho and put radicals together to identify a kanji you want to know from a picture.
Or just use google lens. But radicals aren't too difficult to learn (compared to kanji).
