I have a piano MIDI file which I suspect to be a song from Love Live, but the song name "æSé-é¦Élé¦ì¦é¦Äì" is mangled and my UTF-8 <-> Shift-JIS / ISO-2002-JP converters can't seem to decode it properly.
Nor do I recognize the melody (it's not one of the well-known LL songs). Can anyone help?

I've uploaded the MIDI file here: https://ufile.io/xmx8q
