I haven't heard the full INU. What's the nature of the lyrics?
I haven't heard the whole thing either, but it can be taken as a love song. However, XTH recognize it as theirs, since it lasts 3:20 minutes, and their were hints on the metronome as well.
Here's the first few lines ... Having watched clips of his livestreams with fans, I immediately remembered when he introduced his mom to XTH. I think this is also the song he mentioned in the BtS wanting to hear the audience sing with him. It's very catchy and inspires one to sing along.
Falling slowly, like Autumn leaves
Through every season you've been here right next to me.
You've met my mother
And she told me
You bring out sides of me she couldn't even see
And I still lose my mind, knowing you are mine
Forget what they teach you in school
All the symbols and signs we don't use.
If our life were 3 letters and I had to choose
There'd only be I N U
