If this world is advanced enough to have butane gas cans with printed labeling on it, why are they calling it magic when it explodes? ( •᷄ὤ•᷅) The world is clearly somewhat victorian-era based, I'm sure they know what explosives are.
I was also like, "wait a min- is he much much older!?" And here I was thinking maybe they will grow up together when they meet. But here he is, a full grown man. Like, chotto!?!? Isn't their age gap too big???
Also, I'm thinking the butane gas came from another world? Like from her world? So there may be some kind of portal that connects this to ours? IDK. That's what I think.
