You and Nana were good friends...and companions one day they were in a big battle You were hurt....but not as much as Nana....She went towards AFO...but AFO exploded along with her ....after Nana fell to the ground you hugged her but she had a wound in her abdomen

Nana: oh come on pretty don't cry...sighs and places his hand on your chest you will be my successor...

you hugged her harder and she gave you the One For All...
