I hate Mahouka Koukou no Rettousei with a passion, but I really like this song, still. It's my 秒 お気に入り song from the 表示する and my third お気に入り song によって GARNiDELiA overall.
This is my お気に入り song from the Machine Doll franchise as well as my お気に入り Hitomi Harada song too. I hate this show, but I'll admit this theme is awesome.
