Kamen Rider My-th premiered to broadly positive first-episode notices, with viewers praising the new suit design, the slower pacing, and the episode's careful setup for future plotlines. The show streamed on the Toei Tokusatsu World Official channel worldwide at Mondays 6pm PT / Tuesdays 2am BST, with episodes scheduled to remain available for about one month. Several viewers reported problems with the channel's closed captions, citing visible italic tags in the caption file. Fans also noted and celebrated character moments and choreography in the debut fight, with multiple posts calling the episode a strong, buy-in start. At the same time some fans criticized recent removals of older Rider seasons and warned that taking My-th episodes down after a month will push people toward fansubs and piracy. Others responded with immediate enthusiasm, organizing watch parties, posting fan art and shipping discussions, and planning to buy merchandise. The premiere leaves the series in position to build an international audience quickly but raises distribution concerns that could shape how viewers access future episodes.
