Arcane Force

That's why I said "it's up to Alim to give them or not" and "unless they are like Mifune", and yes the gap between 5* and OE is huge so I can't see Xenon and Estia getting an OE, but still leaving aside Xenon and Estia, as you said, there are plenty more and better units for Mila to give 7*/OE, like Vertri (OE), Rigness (7*/OE), the vocaloids (7*/OE), Mariudeth (7*/OE), Elimo (OE), Shera (OE), Zeldeus (OE), Arius (OE), Faris (7*/OE), Uda (7*/OE), Narza (7*/OE), Nick (7*/OE), Eva (7*/OE), Jack (7*/OE), both Deemos (light and dark) (7*/OE), and so on.

For free units like X&E, Reed's batch would be great to have 7* (I won't put OE on Reed's batch due to the "unless like Mifune" thing), Weiss is another good unit for 7*/OE.

In the end this is just MY opinion so, everything depends on Alim who they wish to give a little of tlc.
