Is Hiro older than Kisa...?

Kisa is one ano older than Hiro. Hiro is 11, and Kisa is 12.

yes Hiro is older than Kisa not por much i don't think about a ano or two~ i think.

I think soo
hehehe

i'll comfirm from my leitura expirence that kisa is slightly older than hiro.

oddly no, but it would be even cuter if he was!

In the mangá Kisa is actually older then Hiro. Kisa ranges from beginning of the mangá to the end to 12-14 years of age, while Hiro ranges from beginning of mangá to the end 11-13 years of age.

In the animê they are also about 1 ano apart in age with Kisa being older and Hiro being younger.

I think Kisa is one ano older
