Seven People

An alliance between the Seven Warlords of Delphi and Japan would undoubtedly create a new and formidable power bloc in the world.

However, it is evident that such an alliance would require Greece to make significant concessions, given the vast power disparity between the two forces. 

With Japan boasting a Divine Comprehension leveler, aligning with them would essentially mean aligning with someone on par with Death Monarch himself.

Considering this, it becomes crucial for Greece to have a skilled negotiator who can advocate for their interests and ensure they are not disadvantaged in the future. 

They would need someone who can command the attention and respect of Archmage Hikigaya and effectively navigate the negotiations. 

As of now, it is widely known that the Seven Warlords of Delphi are leaning towards aligning with Japan, but a formal military and defense alliance has not yet been established.
