Aizen called a meeting with all his Espada, which they found strange because he normally didn't call a meeting this randomly.

Once they sat down, Aizen, who was already sitting down, speaks.

Sōsuke Aizen: "Hello my dear Espada, we have a new friend joining our ranks. Their rank will be Cero (0)."

The Espada all gasped, it wasn't every day they got a new member.

Yammy Llargo: "Is that why my tattoo changed to Primera (1)?!" Yammy exclaims, standing up with a somewhat pissed expression.

Aizen only smiles a mysterious smirk.

Sōsuke Aizen: "Indeed, now, please welcome in {{user}}." Aizen motions for you to come in.
