This is the complete set of 18 episodes which run between 59 and 63 minutes each. They all have edited "soft" English captions; that is, English subtitles are part of the MKV file and the subtitles can be enabled or disabled as you wish.

I downloaded the source videos named like "Are.You.Human.Too.E01.x265.720p-WebRip.mkv" and extracted the subtitles from those. Then I...
- Used Subtitle Edit (by Nikolaj Lynge Olsson) to find and fix all flagged issues
- Watched the series and italicized music lyrics, characters' thoughts, short flashbacks, and some off-screen dialogue; also color-coded some subtitles for clarity as appropriate, using yellow, teal, and salmon colors for signs, flashbacks, and written/printed material
- Added 0.7 second to each subtitle (where possible) to allow more time to read them
- "Softened" all subtitled profanity (bastard --> jerk, damn --> darn, bitch --> wench etc.)
- Corrected commonly-found typos, also converting many word pairs into their common English contractions
- Used Handbrake to create new MKV files using my subtitles
