DanMarch

DanMarch is the het ship between Dan Heng and March 7th from the Honkai: Star Rail fandom.

Canon
They have a relationship of close friends and seasoned partners following the path of the Trailblaze. In in-game content, Dan Heng is seen to care for March 7th through dangerous situations.

The two are paired together in official art & matching profile pictures, released in Version 1.1.

In the animated short Ichor of Two Dragons, March 7th makes a couple appearances; once when Dan Heng is suffocating from the weight of his past incarnation, and then right after, when the rest of the Astral Express crew goes over to him and March takes a picture of Dan Heng, and he smiles.

Herta Space Station
The introduction cutscene of Honkai: Star Rail features Dan Heng and March 7th running to the source of commotion on the space station. The pair later find the Trailblazer and converse while they are unconscious. Dan Heng notes the Trailblazer's weak state and tells March to perform CPR. March refuses and tells Dan Heng to do it instead, only to stop him by pushing his head out of the way when she realizes the Trailblazer has woken up. The two tell the Trailblazer who they are and fill them in on the situation. Dan Heng then leaves to help Arlan.

March 7th and the Trailblazer find their way to an elevator only for it to be broken. March sighs and says how Dan Heng is knowledgeable, comparing him to a "walking encyclopedia" and wonders out loud if he knows anything about elevator repair. Dan Heng appears at this moment and interjects her thoughts, saying he doesn't know anything about elevator repair and instead says that Arlan might. Dan Heng leads them to Arlan who tells them the elevator should start with the encryption key Asta gave them. March remembers that Asta gave her a key, and her slow realization makes Dan Heng sigh and facepalm. While they walk to the elevator March comments on how they haven't bumped into too many monsters, regretting it right after and saying how it might bring them bad luck. Dan Heng sighs and says how she's grown. Right after this interaction a Voidranger sends an attack flying towards the group. Dan Heng quickly reacts and deflects it. More monsters enter the fray and March draws her bow while Dan Heng stands defensively.

In the nick of time Himeko's drone comes and blows up the monsters in front of them. March and Dan Heng nod their heads towards each other in understanding. March pulls the Trailblazer and Arlan along with her while Dan Heng takes a couple seconds to glance at the monsters behind them before running with the rest of the group. Himeko greets March, Dan Heng, and meets the Trailblazer, asking them if March has caused any trouble. If you choose the option that March is reckless she says it's her charm and that you need to get used to it, and asks Dan Heng to back her up. If you choose the option calling her lively, March agrees and enthusiastically asks Dan Heng if he thinks the Trailblazer is a good judge of character. To both these options Dan Heng responds with how he has the right to remain silent. If the Trailblazer says they'd rather not answer Himeko's question, March jokes about how there's two Dan Hengs on the team. Dan Heng responds to this comment by asking to be left out of it.

A Doomsday Beast appears and the members of the express decide to find a way to help. They go to the railway platform and try to meet up with Welt. March runs up ahead to try and take a look. Dan Heng yells at her to wait and outstretches his arm towards her as a gust of wind flies by. The Doomsday Beast has caught up with them and the crew fight it to the best of their abilities. During the battle the Doomsday Beast sends a laser beam towards March. Dan Heng and Himeko scream out for her, and the Trailblazer jumps in front of her and absorbs its attack. The force of the wind forces March to fly backwards and Dan Heng grabs her. The Trailblazer is then knocked out by Welt.

The Trailblazer wakes up and joins the Astral Express. When talking to Pom-Pom the Trailblazer asks about both March 7th and Dan Heng's rooms. Pom-Pom remarks how March is always running all over the place and how you may not find her in her room. Pom-Pom also mentions that the archives room that Dan Heng sleeps in is right beside March's room. When the Trailblazer goes to Dan Heng's room they're stopped before they can even enter. Dan Heng says that people barge in often and so he's learnt to sense when someone is approaching. After Dan Heng lets the Trailblazer use the data bank, he says how he'll be entering new information in it with every journey they take. The Trailblazer says they didn't think Dan Heng to be a scholar, to which he replies that they must have a misunderstanding about him, and that he knows just who planted that idea in their head. If you talk to Dan Heng again he tells you to keep the noise down when you go next door. When the Trailblazer does go next door it seems that Pom-Pom was right as March isn't anywhere to be found in her room.

As it turns out March was in the parlor car preparing for the jump to the express's new destination: Jarilo-VI. March, Dan Heng, and the Trailblazer are assigned to seal the Stellaron on this planet by Himeko.

Jarilo-VI
March tells the Trailblazer to go and find Dan Heng for the trailblazing expedition. When they tell him this Dan Heng shares that Himeko would make him and Welt accompany March whenever she wanted to go anywhere. He also says how even with the arrival of the Trailblazer he doesn’t expect to be liberated of said duty. The Trailblazer asks Dan Heng if he and March could just go, but Dan Heng stands by Himeko’s decision for the three of them to go and assures them that with March by their side the expedition was sure to be eventful.

When the Trailblazer returns to March she asks them how talking to Dan Heng went. If you chose the option that he was full of enthusiasm, she says that's hard to believe. If you chose the option saying he wasn’t too enthusiastic, March says “that”s our Dan Heng” and that he keeps a poker face to look cool. She then tells the Trailblazer to relax because she and Dan Heng have plenty of experience and will help them out. Dan Heng walks up beside March as she and the Trailblazer converse and she stops and looks up at him, her mouth curving into a smile. Dan Heng notices her and asks if he has something on his face, to which March replies that she’s just thinking about their fun adventure. Dan Heng takes another jab at March, saying how he feels sorry for how this world they're visiting needs to deal with both the Stellaron and her.

The Trailblazer has two dialogue options when they reach the snowy surface of Jarlio-VI. If the Trailblazer asks why they didn’t land directly at their destination, Dan Heng turns to March and asks her if she wants to share how she made a hole right through Taikiyan Stadium with the Trailblazer. March sighs and tells him to not bring it up… only for Dan Heng to also mention how she did two weeks of community service as a result. If the Trailblazer says how they didn’t anticipate hiking, March agrees and says how much easier things would be if they had a snowmobile. Dan Heng brings up their previous snowmobile to March and she tries to change the topic. Dan Heng reminds the group to remain vigilant, and March tells him to not worry because they’re a good team, and she references his mysterious past.

As they trek deeper into the show March notices an alleged snowdrift. March tells the person in there to come out but they remain hidden. Dan Heng tells March he's got this and stomps on the snowdrift, discovering Sampo. They are all unimpressed with him as he rambles and March asks him to take them to the city. Sampo begins to go on another tangent and starts talking about how such an escort would cost them, but Dan Heng shoots him a glare and Sampo decides to take them. They get stopped by Silvermane Guards and Sampo runs away, leaving the three behind. They get caught by the guards and their Captian Gepard who lets them determine their fate after meeting the Supreme Guardian. When they enter the city of Belobog, March comments on how its gotten warmer and asks Gepard what he means by calling the city humanity's last bastion. Gepard explains Belobog's history and March looks over at Dan Heng and tells him how he's saying some weird stuff. Dan Heng glances back at March and notes how Gepard's tone changed, as if he was reading from a history book. March agrees and asks why he was telling them this stuff in the first place. Gepard says she was the one who asked. March smiles and shrugs, and Dan Heng closes his eyes and looks to side.

When they reach the residence of the Supreme Guardian March asks to freshen up before seeing her. If the Trailblazer asks to tag along Dan Heng says how they shouldn't waste time. If the Trailblazer tells March she looks fine Dan Heng tells March she has snow in her hair, but it's not noticeable. They get approval after reaching an agreement with the Supreme Guardian and wander around the city. They approach a workshop and March wants to watch an outdoor performance because Gepard said they had them sometimes. Dan Heng reminds her that Gepard said it was only sometimes. They continue sightseeing and Trailblazer rummages though trashcan that has a flyer promoting an organization that will help you get away from friends and family to pursue whatever fun you want to have. March says its thoughtful and how she'd like to spend one day doing whatever she wants, to which Dan Heng responds that she must mean wanting to sleep in. When they walk back to the Goethe Hotel March yawns and says how tired she is. She addresses Dan Heng and reminisces to him about how the first day of their expeditions are always eventful. Dan Heng chuckles and says it’s because March has too much energy.
