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. The group of them make it back to the elevator and Arlan chooses to stay behind while the others go on ahead. March and Dan Heng adamantly refuse. With some encouragement from them and the Trailblazer, Arlan moves on with them. While they walk 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 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.

Fanon
Many fans are brought in by the dynamic of March's bright, lively personality, which contrasts Dan Heng's more reserved, cold personality.
