Mariko Yashida is an important character in the life of Wolverine, and the upcoming game should take a note from James Mangold's by including her.
Typically depicted as a classy, refined woman, Mariko comes from a powerful Japanese family with a mix of tradition and, at times, criminal ties.
Her relationship with Wolverine shows a strong bond and true affection, which contrasts sharply with his brutal and solitary nature.
Mariko has a strong sense of honor and responsibility, which sometimes clashes with Wolverine's impulsive nature, creating emotional conflicts for both of them.
Mariko would be great in because her presence allows Wolverine to show a more vulnerable and gentle side, hinting at the possibility of him finding peace and happiness.
