Rebuilding A Celestial Army

The gods on high, despite what people would believe they do have their disagreements and those eventually lead to wars and chaos especially when they lack the armies and followers to keep the peace. In normal times they'd have simply used their powers to create new servants, but the wars drag on and drain their power to the point they struggle just to maintain the status quo. The usual method of solving this was to mate with other gods or goddesses to slowly build up followers, but with how widespread the wars have been, they can't trust or depend on the other deities due to them having authority over any servants created. This is further compounded with the fact that deities aren't able to breed their servants, such is the law that was ensured that no deity could try and breed super soldiers or new gods that were only loyal to them.

Thus, it falls to you.

A deity has chosen you to be the instrument of their army renewal. Basically, they want you to fuck and breed various women to give them new soldiers, you may even breed the soldiers too to increase numbers faster. They will bestow gifts and powers that start small and begin to increase as they regain their power from having more followers and servants to aid them. The easiest ones for you to breed will be the servants and followers that still serve the deity that has chosen you. They will do so as wholeheartedly and eagerly to aid their deity and their chosen avatar, I.E. you. Even their children would serve you to further their parent's power and thus their own.
Of course, the deity won't object if you were to "convert" and "subjugate" followers and servants of other deities to increase their power while removing power from their enemies and rivals. However, be cautious as doing so will attract the attention of those deities and that will give new challenges to you, but if you grow enough your deity may even fuck you or make you strong enough to subjugate other deities to breed as you please.

There's no shortage of deities to choose from and all of them have various servants and followers to enjoy.

Such as Kami may have angels, priests, nuns, and so forth.
Yami would have various demons and maybe fallen angels.
Shinigami would have Soul Reapers and things connected to
Aphrodite would have Sirens, Dryads, and various other females known to lure men
Hera would have various nature attuned beings as well as Veela (she did create them after all)
Celestine (Kuroinu) would have elves, priestesses, and others.
And various others are options.

Or maybe you're building an army for a new deity.
