"Beo, I overheard their offer. With our recent activity, maybe having a group which we could claim we are not affiliated with doing missions against certain foes might prove beneficial." Using his words delicately, with their take over of Nebo, The Soul Society will likely get aggressive, so using this group as a buffer against the soul society, and even as a attack force would be useful. As long as they couldn't prove a connection between the Espada and Mercenary group, the group could be used to wage a proxy war. Or even use them to take out certain targets in other soul societies to weaken the defenses so that the Espada would have an easier time at conquest.
"But I dunno, these guys don't look half as strong as us... Don't you hire people becasue you lack power?" Willow said a bit insultingly, "Oh my, that was rude. Forgive me." Willow bowed again, "Sorry for the interruption, Bye bye!" Willow broom appeared in his hand and he took off into LN.
