This news may seem sudden... but this world died long ago. Earth died a thousand years ago, and a legendary clockmaker known only as "Y" rebuilt it using clockwork. Miura Naoto, a failing high school student, encounters Ryuuzu, an automaton that "Y" left behind, and the genius clockmaker Marie. When the abilities of these three come together, the gears of fate begin to turn. The cycle of failure and success repeats endlessly as the three of them work to repair the endangered "Clockwork Planet" in this clockpunk fantasy! Source: Crunchyroll
Theoretical best: JPN BD+DameDesuYo/LostYears
SCP-2223 is ReinForce+DameDesuYo (E1-4), CR (E5-12). Subs are a few frames off throughout. LostYears subs are DameDesuYo with improved TS (E1-3), modified CR with DameDesuYo styling/KFX (E4-12) The show is super grainy so pretty much everything except the JPN BD and ReinForce fall apart
