很遗憾,根据我目前的资料,《星辰变》动画 apparently only has two seasons that have been officially released. It seems there isn't a third season available to watch online or otherwise at this time. The series is adapted from a web novel of the same name by Icy Blaze. You may want to check official sites or authorized streaming platforms in case a third season gets announced and released in the future.同时，我也找不到《星辰变》第三季的在线观看资源。这可能意味着目前还没有制作第三季，或者它尚未在任何授权平台上发布。你可以关注官方渠道的公告，以便在将来第三季宣布并发布时获得最新信息。
