I loved the yugioh og reference at the end.
Yami Teruko best girl.
For all you weebs/pronoun fanatics, Taiga calls Teruko "mou hitori no ore" where as Teruko calls Taiga "mou hitori no atashi". (Alas, no AIBO).
"Mou hitori no ore/atashi" means "Also the one me," so it makes more sense in this context
It means "The other me".
For reference, Yugi use "Mou hitori no boku" when talking of Atem
