This girl later appears in the series’ ending alongside Maki while the latter cradles what appears to be a marigold to her chest. Of the many interpretations of a marigold, the most common are related to pain or the death of a loved one. Victorian-era flower language links it to the ill-treatment of a loved one, while marigolds are still commonly used to celebrate Mexico’s Day of the Dead, which honors the deceased. Maki’s personal issues appear rooted in guilt over this one girl in her past. While her part in the girl’s apparent death is unknown, this incident is something that Maki is obviously still chained to, which is further reflected by the marigold flower.
