These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ear Worm: Most of their songs, with Doki Doki☆Morning and Headbanger!! being the most catchy.
Ensemble Darkhorse: Of the Japanese Pop Music scene, as they are the only ones (so far) to have successfully fused J-pop and metal and made it sound legit (and awesome) for not just J-pop fans but also for metalheads.
Fan Nickname: The genre of the music they play is usually called either "kawaii metal" or "moetal", among other names.
Rescued from the Scrappy Heap: In a genre dominated by many derivative acts, their unusual approach has earned them their own niche in the J-pop scene, and better reception compared to their contemporaries.
