>>27855120That's a /toy/ chuba, and gunpla belongs on /toy/. An /m/ chuba is either a robot themself or thematically tied to robots, and has content that panders to a broader /m/ demographic.
If the only /m/ thing about a chuba is that they play with toys, that's such a narrowly defined subset of /m/ that it's just not sufficiently /m/. Being /m/ is a lifestyle, not a casual interest, much like being an idol is. Just casually singing a few songs here or there once in a while doesn't make someone a full fledged idol. It takes far more than that to earn such a respectable title,otherwise everyone could and would be an idol and the term would lose all meaning.
