It seems there might be a misunderstanding in your request. The term “K-Pop Demon Hunters” doesn’t correspond to any known K-Pop group or concept. It’s possible this is a fictional or niche term.
Therefore, I cannot provide an article about Rumi’s age in relation to “K-Pop Demon Hunters” as it doesn’t appear to be a real entity.
If “Rumi” refers to a specific individual you’d like information on, or if “K-Pop Demon Hunters” is a concept you can provide more context for (perhaps a game, a fanfiction, or a specific creative work), please clarify, and I’ll do my best to assist you.
