Objective: Defeat the Devil Yurine (?)

Recommended Echelon(s): AR/SMG

This is a little bit of a disappointing last map compared to something like the va-11 hall-a collab. But what can you do? Anyways, our goal is to defeat devil Yurine, but she's a mile from us. Thankfully, it's a fairly simple path. We have our starting area that we can see and then a veiled area between us and devil Yurine. The places to unveil them are each of the Radar Towers, and they only reveal a partial amount of it. Now, from what limited testing I did, the correct Radar Tower is usually the same, but it changes once you've cleared the map once. So, prior to map clear, the correct Radar Tower was always the right Radar Tower. After map clear, it is always the left one. Again, take this with a grain of salt, as I didn't do a billion tests. Anyways, assuming you get the correct Radar Tower, it will unveil the entire area instead of just partially. Anyways, onto the map itself.

As I mentioned, this is fairly simple. Swap your echelon with Yurine and capture the Heliport nearby. You can let the one AP be wasted just fine. Turn two, head to the right most Radar Tower. This should unveil the rest of the map. If not, check the rest of the Radar Towers. Ouro should show up now and you can swap with her to get closer to devil Yurine. Engage her when you can. If you allow her to get to the shaved ice, you can get an achievement. Long as you kill her after she eats it.

Devil Yurine

She's a fairly simple boss on normal, but if you're lacking in firepower, you may need to do her mechanics properly. 

She mainly shoots you while summoning additional enemies. Be sure to retarget your ARs via moving them when the enemies spawn in, so you're not overwhelmed by them.

She'll also stun two of your dolls in the back column. When she does that, she'll then pulse an AoE attack in the first two columns of your side of the battlefield. The way to avoid this is to actually move your tanks into the dolls that Yurine stunned. Since they're stunned, they can't move, so you're safe from the attack. Once she uses the AoE twice and the stun wears off, you can move your dolls back to nnormal.

Defeating her will clear the map.
