Summary
The release of Sunday’s playable version inHonkai: Star Railmay happen sooner than originally expected as a new leak makes a previous one obsolete. Sunday has already been introduced as an NPC during the main Penacony story arc and has huge significance. While he has not been seen following the fight against theHarmonious Choir boss inHonkai: Star Rail, it is known he is alive and well. Players have yet to see Sunday again, but his reappearance may occur within a few months.
According to a new piece of information provided by Seele Leaks, which was shared in a post tagged as “Questionable” onReddit,Sunday should be the next 5-star character presented in Version 2.6– for reference, in Version 2.5, Feixiao and Lingsha are already confirmed to be the new 5-star characters. If the leak is true, players may gain access to the playable version of Sunday in late October, if he is presented in Phase 1 character banners of theHonkai: Star Rail2.6 update and not Phase 2 banners.

Why I’m Not Excited About Honkai: Star Rail’s Dating Sim Leaks
New leaks about Honkai: Star Rail suggest a dating gameplay mode similar to visual novels, but it may not be as exciting as you initially think.
Sunday’s Release In Honkai: Star Rail Has Been Leaked
The Character Was Originally Expected To Arrive In A Later Update
The mentions of Sunday’s release in Version 2.6 may be great news for players who are eagerly expecting him.The first few leaks about Sunday’s playable version expected the character to arrive in Version 2.7, essentially six weeks after the most recent prediction – if the game sticks to its six-week schedule for all upcoming patches, the leaked Version 2.7 release prediction would mean Sunday would only arrive inHonkai: Star Railin early December.
At the moment, not much is known about Sunday’s playable form in the game. The previous leaks stated that Sunday would undergo an outfit change for his release as a playable character, boasting mainly darker colors as opposed to his traditional bright white and blue suit, worn by his NPC form. The previous leaks also stated that Sunday would be an Imaginary character who followed the Harmony, which would make him a support unit. However, a newer leak by Seele Leaks, also posted onReddit, mentions thatSunday may not use Imaginary DMG inHonkai: Star Railafter all.

It is hard to predict exactly how Sunday will presented in his playable form – especially considering the lore-related implications of his role in Penacony and what happened after the conclusion of the story arc.More reliable details about Sunday and even his gameplay kit should start arising closer to the release of Version 2.5when the beta tests for Version 2.6 start.
Of course, if Sunday’s playable version appears in the beta tests, this will confirm the current leak.

For now, all of the leaks related to Sunday should be considered with caution as a lot of the information may be incorrect or subject to change – especially because he is still likely months away. Nevertheless, the constant mentions of Sunday’s playable form indicate it may be true and those who adored the character may finally be able to use him – even if only sometime after they get to useFeixiao inHonkai: Star Rail2.5.
