Star Rail faces a fork in the road with Team Synergy on Sunday

While Honkai: Star RailVersion 2.6 is such a big update, people are already pining for the release of 2.7 in early December. That patch will finally release the much-anticipated fantasy-harmony unit Banner: Sunday. Playable unit releases and updates for established characters like Sunday are often hyped because their kits and designs often match their progression. Honkai: Star Railthe story of For example, the companion 2.7 unit Fugue is all but confirmed to be a reincarnated or crossed version of Tingyun, a character who appears to have died during the events of the Xianzhou arc. Developers can strengthen Sunday's lore by playing with his synergy with an existing supporting character that plays a larger role in his overall story.




Players don't know for sure what the plot and kit will be on Sunday in 2.7. However, this is indicated at a later time Honkai: Star Railof the Penaconi plot that he could be freed from the family's prison by Jade. Some fans think he'll join the Stellaron Hunters, while others think he might bunk with Team Akvilly on the Astral Express. There have also been rumors surrounding his kit from reputable leaks such as HomDGCat and Seele Leaks, suggesting that the unit may contain energy-generating ultimates and action advances that affect summons.

Honkai: Star Rail can hint at Sunday's lore through his kit


After the events of Sunday's boss fight, a title card hinted that the brother and sister were “doomed to eternal separation.” This probably refers to Sunday and Robin, as the former was arrested, tried and imprisoned by the family after his crimes came to light. Developers can explore this story by complementing their kits or competing with their siblings.

Developers can hint at Sunday and Robin reunions by making them synergistic

Some fans just want to get Sunday so they can use him on a team with his sister. The gods could give them what they wanted and make the two work well together. After all, Sunday's potential energy-generating ultimate could help fill Robin's 160-energy ult requirement as quickly as possible. Sunday's potential action-enhancing skill can also work well with Robin's ult, as both abilities give large buffs and significant extra turns to their teammates. This synergy can be used to reinforce a more optimistic story where Robin is reunited with Sunday and helps in his redemption.


Alternatively, the devs could play in the “Eternal Separation” storyline and have Sunday compete with his sister for the harmony support role. This seems more realistic, as Robin's team-wide buffs are currently geared more towards dual-DPS compositions like Fixiao-Topaz/March/Moz and Kafka-Black Swan teams. Sunday, from what can be gleaned from his leaked kit, offers single-target buffs that make him more geared toward single-DPS hypercarry comps. Also, according to HomDGCat's recent leak, Sunday's skill-based action advance will not work on other Harmony units. His ult can also provide large CRIT DMG buffs, so it's best used for a damage unit that can use it instead of Robin.

Information about Sunday's capabilities is based on leaks from reliable sources, but they should still be taken with a grain of salt. All pre-release information is subject to change until the character's official launch.


From the looks of Sunday's leaked capabilities, the siblings may be separated when it comes to fighting games. The devs and writing team could use this to lean into the siblings' tragic story. Maybe they can write in a reunion with the two realizing they're just meant to walk different paths. Either way, that doesn't stop dedicated fans from slotting the Oak siblings into the team and somehow making it work.
