If you want jp audio or subs based on jp audio, it’s better to directly get Subsplease/Erai-raws.

Modifications:

For Tencent subs, I retimed, added missing lines for Insert Song in Ep 00 and Ep 08, restyled op ed insert and took signs from [Erai-raws] Chinese Ver.
For Hectab, I just retimed (less work compared to tencent ones), and took signs like above. I am adding it for preservation’s sake. Personally, I havent done a compare of old vs new Hectab subs but it’s v2 cuz Hectab said he updated files from episode 0.

I wanted to rewatch this before Season 2 gets released, so I looked for old tencent raws but could only find tencent 4K which is just alright or oversharpened in few scenes for me. So I looked up for crunchyroll videos. These are same/better than what I remember of old 1080p raws from tencent. Quality is somewhat bad for initial episodes but it becomes good later on. Anyways this one is good to go for a rewatch.
