So I was looking at the lyrics of Stammi Vicino just before in the Oh! スケトラ!!! album book and I ended up reading some of the lyrics I hadn’t properly looked at and I’m killing myself over Phichit’s ‘Shall We Skate?’ xD
'Your dreams will come true if you believe in, like a magical trading card game’
If I didn’t know any better, I’d think that was a direct reference to Yu-Gi-Oh….
