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: A tune plays in the room where Li stores all Sakura's magic-related stuff. Supposedly it's the same tune that played when Sakura confessed her love for Li, most likely making it Ashita He no Merodeii. Li even sings a dubbed version of this song when Torika finds him out at the end of the Heart Arc.
Fanon: Both the second movie and the Nelvana dub happened, despite that the two are nearly irreconcilable.
