This can only be triggered by story mode, and the combat mode (that is, the person you choose) cannot be triggered.

The specific details are that Otto's signature is only at the level of 1 1 in the story mode, and Taylor's "Otto Heroes List-Beyond Otto Brothers"

You can only send it at that level, just press the R 1 key. Keywords Zofi, the first generation, Severn, Jack,

Ace, don't forget to press the R 1 key to send Otto's signature when fighting the tyrant. If Zofi forgets,

Hair, then the second round, the first generation will be beaten by tyrants, will lose 50% of the blood, the first generation will not send.

Severn was beaten, Severn didn't send it. Jack was beaten, Jack didn't send it, and Ace was beaten. This will be a vicious circle.
