I wish I was able to find subs like this for other shows, specially some of the sentai shows I’m watching/planning to watch, as I feel this may be one of the most fun ways to immerse in Japanese.

I mean, you have the text with kanji on the bottom plus the characters speaking, so that takes care of the guess work of how to read the kanji, and even if you don't understand clearly what they're saying in terms of how to read the kanji, the presence of the text means you can easily just print the screen paste it onto an OCR and use it to look up whatever kanji you're looking for.
