Should this also be tagged with Honkai Impact? I feel like that tuna and that hair is a strong reference to Kiana...
I might be wrong, but it might be a reference to another artist's Doctor (who has this hairstyle, and has Red as one of the protagonists of their comic), as both this artist and that one are active members of the Arknights subreddit, and it might be a "crossover". But again, I might be wrong.
