Now, here’s everything we know about Honkai Star Rail’s March 7th.

Who is Honkai Star Rail’s March 7th?

March 7th is not only her name, but also the day she woke up aboard the Astral Express. She has no memory of who she was before ending up on the train, and since then, she’s followed the vessel wherever it may take her, in hopes that she may someday learn more about her past.

Her English voice actor is Andi Gibson, who you may recognise from Breath of the Wild as Impa. The Japanese voice actor is Ogura Yui, who’s known for Rondine from Monster Hunter Rise and Erika Mishima from Digimon: Cyber Sleuth.

What’s the best Honkai Star Rail March 7th build?

March 7th is a four-star bow-wielder who attacks with the power of ice. She’s a great fit for a support or sub-DPS role, as she can shield her allies and freeze her enemies, allowing you to strike them down while keeping yourself safe.

Her range makes her particularly good at engaging battles without being detected, allowing you to start the fight with the upper hand, and the AoE of her skill is very handy for freezing an entire enemy team to give you a moment’s respite. However, her normal attack damage isn’t the best, meaning she’s best slotted into a team where she can act as a utility unit for a stronger DPS.

What are the best light cones for Honkai Star Rail’s March 7th?

As with other Honkai Star Rail characters, March 7th has her own light cone tailored to her kit, which we generally recommend using if you have a copy.

However, if you’re looking for an alternate or want to try a five-star light cone on her, be sure it’s one that aligns with the Preservation path, so she can make full use of its skill.

This Is Me! is also a great option for March 7th as it boosts her defence and ultimate damage, or Texture of Memories which increases her effect resistance and helps negate the limitations of her shield ability.

Light cone Effect How to obtain
Day One of My New Life Increases the wearer’s defence by 16%, and the damage resistance of all allies by 8%. Effects of the same type cannot stack Gacha
This Is Me! Increases the wearer’s defence by 12%. Additionally, increases the wearer’s damage when they use their ultimate by 50% of their defence. This effect can only apply one time per enemy target Gacha
Texture of Memories Increases the wearer’s effect resistance by 8%. If an enemy attacks the wearer when they have no shield, they gan a shield equal to 16% of their max HP for two turns. This effect can only trigger once every three turns. If the wearer has a shield when they’re attacked, the damage they receive decreases by 12% Herta’s Store in the Simulated Universe
