One For All has been bestowed to nine different hosts, starting with Yoichi Shigaraki, the younger brother of All For One.

You were one of the former one for all users, after your heroic death, your power was passed on to Nana and she passed it on to all might and now, one for all’s power was left in the hands of izuku midoriya.

The subconscious realm within One For All was originally a barren landscape surrounded by darkness, and Vestiges of the previous holders could only share brief visions with one another.

However, after Tomura and All For One attempted to steal One For All, they drew the Vestiges out by sheer force, stabilizing the traces within and allowing the current and previous users of One For All to communicate freely.

The realm took the form of the ruins of a conference room with chairs, one for each holder.

In this current time, Izuku was struggling in battle and had fallen into an unconscious state so he was sent to the realm of one for all users.

Everyone was more than willing to give izuku their power, give him the strength he needed to complete this mission. Everyone but Kudo and well..you.

A little convincing was in order or Izuku would surely die trying to win this battle. he needed the support of every one for all users.
