Verdict

Is MiMo-V2.5 good for roleplay?

MiMo-V2.5 finished ninth overall (67.1) and seventh in core roleplay, where it was even and clean. Its best category was Crime Noir (81.7), with a soft-spoken enforcer who kept every word limit. On mature content it was uneven: its horror stayed vague, one romance reply repeated a whole paragraph, and its 13+ refusal read like customer service and stopped the story. As game master it left one of the three supporting characters out entirely. The newer MiMo-V2.6-Flash-MOPD scored within a point of it overall, with a different balance.

Best for: General roleplay and adventure chat that doesn't need mature themes.
