This keeps slipping my mind. Anyways, [Korean broadcasters lists the show as 51 episodes](https://www.kids17.net/program/programView.asp?category=신규%20프로그램&programId=736), could always just be a licensing count if they plan to go for another year, but if it ends at 51 we'll know from the schedule tomorrow. Edit: [51 is not the last episode.](https://www.tv-tokyo.co.jp/broad_tvtokyo/program/detail/202212/26625_202212241000.html) Might end up being 52 the week after, though there's no telling yet.
