It's a little funny how she's harder to spam attacks against than Tsih and maybe even Mira; I believe you'll spend more time dashing than dash-attacking. She starts her fight with immediate machinegun fire at Sora. She summons drones that quickly fire lasers everywhere, and she has a short charge time before meleeing you.

The only other attack of note is that she fires missiles upwards for those to rain down on Sora shortly after.

Please let me know if that drone with the spotlight does anything important besides present a challenge for an achievement

Her glowing stealth mode prevents lock-on, but she can still be hit by your attacks.

She flashes some thin lines which show where her rocks will come from. Those can punish you for keeping your distance. I don't know the best way to deal with those.

While Alte punishes you for not dashing, Mira will punish you for moving too fast, moving too slowly, and getting too close. They start by teleporting behind you then firing big sawblades that "crawl" to the edge, around the edge, then in your direction. The sawblades also fire energy attacks. Mira also has a combination of knives, energy beams, and the occasional tornado

at their third bar, they will surround themselves with their sawblades, and then throw those at you at much faster speeds.

On another note: if you've unlocked the "match" mode in the main menu, you can practice the quirks of your weapons against bosses. Special (including melee) weapons seem to have the most variation

Meleeing her wisps seems impossible to do safely. Her little square barriers explode at their end; until then, those block your movement without damaging you

Lots of attacks. The shields at the beginning reflect your laser attacks. You quickly learn that her giant missile-launching arm blocks damage. Nath also breaks lock-on when flying up to switch sides.

Her 3rd health bar fires more missiles than usual, and her arm charges up a massive energy explosion. There's more, but the gist of it is that you have even less time to attack her than before. Good Luck

Thankfully, those bombs no longer explode in columns and rows. I think you can dash through those lasers but not those explosions at the end. You definitely need to get a good handle on the movement system

1st bar: single target. Those arms prevent you from clinging to the edge, especially the top & bottom. They spray bullets everywhere. Thankfully they don't attack when retracting.

2nd bar: The extra targets have large sprays of fire; you cannot dash through the sprays, only the bullets. You only need to focus on attacking the center. Keep an eye out on which node will spray fire next.

3rd bar: Starts out light; you can lock-on to & melee those drones with the homing lasers, but the timing can be tight. Later Star Breaker brings out those massive missiles and a massive beam. The missiles seem to be safe until those reach the edge. Unlike previously, You can dash through the center laser to charge your hyper unless if a missile is hiding under it. As far as I know the safest timing to use a non-main hyper inside the laser is to press the hyper + weapon buttons at the same time, not shortly after or before.

Those chains are fast and sometimes block your attacks; you do not want to be near the same row as her when she fires those, but she also uses those to punish you for dashing too much and staying near a corner. You can't dash through her blue shots, but I'm not sure if those are also blocking your attacks. When she combines her blue shots with those lasers, the blue lasers will fire in the 8 compass directions while the red lasers fire between those. Prepare for your hyper gauge to charge and your heat to go up

You will need to multi-dash to deal with those big spinning flowers. An easier way is to waste a hyper then dash to the top of the screen (I have no idea how the community would feel about that tho).
