Record of the Agarest War and the sequel are both rather Disgaea-like.

The same company makes a few other SRPG's that might be worth checking out, but they are rather pricey. I have the first Agarest War and the combat is kinda different. Your characters have more powerful attacks if they are linked to other characters and each character has a different positional grid that will link them to other characters depending on their position on the map. Watch a vid or two before you plunk down the 15 bucks.
How does 98% of people ITT not know how to link a game?
For example, my favorite
LinkMe: RPG Record of Agarest War
Ok, bad example because even when you give the exact name of the game, it stills shows FF Tactics. This is what I'm talking about https://play.google.com/store/apps/details?id=com.hyperdevbox.agarestwar&hl=en
Agarest War and Agarest War Zero, if you're into JRPGs
Try this one. The Dev also has a few others in this style
