What happens next basically has nothing to do with Reiger.
Whether it's the process of forming an alliance or the discussion about going to war, these are not matters Reiger needs to worry about.
Just like when he was with the Loki Familia, although Reiger participated in strategy meetings between leaders and executives, the ones who truly decided the details of the operations were Finn, Revilia, Grace, and others, not him.
Therefore, now that Noconalay has decided to form an alliance with the Round Table, Reiger no longer has a need to be involved in the subsequent matters.
He only needs to wait for the discussion to end and for someone to tell him when the war is actually starting, and that will be enough.
And these matters are naturally for Da Vinci, Matthew, Fujimaru Ritsuka, and Noconalay to discuss.
