These? You mean all of Matuena's works? What has been translated can be found on pretty much any manga reading site.
- Tatakae! Ryouzanpaku Shijou Saikyou no Deshi: fully translated, quality is kind of okay with some miner errors as far as I can tell.
-Shijou Saikyou no Deshi Kenichi: This one was translated long before ebooks were a thing. Image quality is garbage most of the time and the same goes for the English translation. It's been worked on by many groups and some were better and some were goddamn awful.
- Tokiwa Kitareri!!: Again horrible image quality for the first part, because the first group used Chinese overfiltered speedscans. Their translation is rubbish as well. Got better after that until one machine translating groups tok over. Was dropped by everyone at chapter 38 of 120.
-Kimi wa 008: Current series, still ongoing, but the translation is very slow. 36 of 90something chapters have been translated. Translation seems mostly decent.
