MYU Mk.2

An improved version of the MYU robot fought during the Battle of Destiny, this is the last boss you will fight in the True End routes prior to the final battle, and its appropriately as tough as it would seem from that fact alone: its stats beat the ones of its original version by far, and to make matters worse, it has the best properties of the pre-Mode Shift and post-Mode Shift MYU without any of its weaknesses. In other words, it has a monstrous resistance to both Song Magic and physical attacks, as well as high resistance to all elements excepting Wind, so if you're playing in Hard, most likely using the Ultra Supermoves for all your Vanguards and high-charged Flipsphere won't be enough to destroy it, and you'll have to repeat the procedure to finally kill it off.

Likewise, it hits very hard and can inflict all stat ailments upon hitting any of your characters, not to mention all of its attacks have quite a wide range, so the best you can do to rack up Beat Ups and do some damage while you execute the Purges and wait until the Burst Gauge has charged enough is getting behind it. That way, most of its attacks won't hit you, although you will have to be careful for whenever it turns around. And like its predecessor, its Ar tonelico Ver. 1 Stored Attack will utterly wreck you party if you don't keep your HP up, so be careful with it, although if you want to try interrupting it, make sure to bring a large stock of Wind-elemental attack items, particularly Stormbringer Buttons, and that should make the task much easier, even in the higher difficulties.

Finally, this time around you won't to worry about a time limit, so just focus on keeping yourself alive while you attempt to destroy it.
