hmm its funny though how if you really think about it... the two characters we have both seem similar to each other

for example rather than being the son of a pro-duelist Shinrei IS the pro-duelist

Both brothers care deeply about their sister

Both brothers have a history with their father (though Hayato's was more neutral)

Both brothers are protective of their sisters.



both sisters were cut-off of being able to make friends (well Hayate did sneak out sometimes to buy cards but really she had no time to talk to people when she did)

Both sisters have some sort of personal defense though Hayate's Toy Hammer is probably a bit more painfull than a paper fan, and both of them is either good at fighting or is really fast at running though Hayate is more of a runner than anything else but as evidenced by Vincent she can pick people up without even noticing it

Both sisters would prefer if their brothers acted more like their old selves

Both the brothers and sisters could pass for each if they colored their hair

though since i dont have a picture of the 2 of my characters nor could i find one that could pass for the 2 of them, you have to assume that Hayato is a cool looking character rather than handsome, and Hayate is more cute than anything else

forgot the mention oops (also there should be a few others that i cant come up with)
