Has a lot of shounen and specially medieval fantasy type words, though most are fairly common in isekai light novels. The game interface itself is pretty easy to understand, but the dialogues can be a bit complicated sometimes. Overall not too bad, just many words that are specific to the genre. The opening with the narrator is particularly difficult though. I'd recommend playing with the game script opened in a browser to make lookups way faster. To find the script look up the Japanese title with 台詞 / セリフ If you want to use an OCR to scan the in game text you'll usually have to use Google's OCR since the font is so pixelated. I'd recommend the Lens app.
