Okay so Youkai and Butterflies behave the exact same.

In the following instance, I put a formation down and summoned one youkai and one butterfly. At the beginning of my next turn, the Tactics Rank Increased.

In the next, I tested an Attack Order on the Youkai. I couldn't get a butterfly to hit. But I believe on the off chance it does, it will also increase the tactic rank on hit (And apply damage bonus in both instances.)

The final instance, I tested cast order which led to the same result. Increasing Tactics Rank. When the youkai used an ability such as Acid Jet.

However Charge Order, despite giving them the movement bonus, did not increase the Tactics Rank.

(Guard Order is useless as the youkai or butterfly will never guard despite having option to. Coding I assume.).

I[strike]nteresting to note, despite having all three spots on the formation occupied by Allied Npcs, I did not get the additional crit bonus. It continued to read the same result as if I had no allies. Having one ally and one Ally NPC only lead to having a 2x bonus as it is suppose to with a Tactics Rank increase at start of turn.[/strike]
Either the hud was bugging or I wasn't paying attention, but the bonuses are now working correctly 100% ally wise.
TL;DR
Here's a cute lil' table.
