Sunday has been one of the most anticipated Penacony characters in Honkai: Star Rail, largely due to his unique personality, compelling involvement in the storyline, and the fact that he was introduced as a playable character later than the rest of the cast. The anticipation has paid off, as Sunday proves to be an exceptional support unit. His abilities not only enhance hypercarry characters but also significantly boost summons, a feature expected to gain prominence in the evolving combat meta. This is especially relevant as players explore the new Remembrance path, set to redefine team strategies starting from version 3.0.
