well he didn't admit it actually. he conceded 2 out of my six points till i called it a day with thread nearly being closed.
seriously think about this:
-takuma came first
-was not given a name in the beginning, he was a nameless boss
-was introduced as someone who fought in the same style as the hero but his moves were faster and stronger
-he wore a demon mask
-his name was takuma later on
-he was related to the protagonist
-he ws trying to unleash the hero's true strength (i.e. haohshikoken)
flashfoward, akuma:
-his name was (t)akuma
-was introduced as a nameless boss
-fought in the same style as the hero with stronger and faster moves
-was demonic in facial features
-related to the protagonist
-he was trying to unleash the hero's full power
anyway, so what you been up to? it really has been a while hasn't it?
it was canonical actually. he plain outsmarted them.
