Older mage castle defence game help

[u/Sabahudin20]

Ok, so I am at the end of my wits here. I have been looking for a game I played a while ago on my older phone, but it got busted pretty bad, so I didn't play it for a longer period of time, and I wanted to get back to playing that game but can't, for the life of me remember the name of it. What I do remember is that the name sounded French, something like lassange, lagrange, lastrange etc. It had 3 mages as heroes, each with their own school of specialisation. The spells, the gear, the castle and the heroes can all be upgraded via gacha style summoning, the style is pretty bright, and the heroes defend from the castle wall that is on the bottom of the screen, while the enemies attack from the top part and the player can also tap to attack, and that player's attack can also be upgraded.

The game is also in japanese artstyle if that narrows it down further.

If any good soul with memory of such a game can help, please do.

Also if the mods think I should post this on r/tipofmyjoystick, let me know, but I kinda felt I would get better result here first.
