The seventh boss, The Burst is a huntress trying to play a game with you who is probably also the hardest boss in the game. This boss also features other enemies aside from the boss in the form of drones who shoot a spread of bullets at you, which are indestructible on Furier, on top of mines which create a ripple wave when triggered by standing close to it, as The Burst herself tries to snipe you from afar. The first three phases have you chase her around the massive arena as you try and trace her position using the incoming line of fire. I don't really like the randomness involved in what end of the arena The Burst will snipe from. In a game about speedkilling, this randomness seems counterintuitive unless you can somehow control her by predicting or abusing her AI, but I've not really found how to do it or whether it's possible to begin with. Even though positioning can be used to set up the boss to be more vulnerable to your attacks, the arena here is too large to have any idea how to really control The Burst.
But if you do chase down the burst and attack her right after she fired her sniper rifle, the fight shifts to the arena you're standing on as The Burst peppers you with a stream of purple bullets you can parry through, or red bullets which turn into wave zones but can also be parried back (the first one at least). After that it's mostly shooting up until she initiates another massive wave attack, but as usual you can skip that one if you dealt enough damage. This repeats for the first three phases, but later phases also see mines and white drones which fire homing bullets. If you hit The Burst during the third phase, she will instead run towards the center where you're encouraged to run towards as well, as she tries to snipe you down. It's mostly bullets you have to parry back, but there's also a neat trick where you can shoot The Burst in her face as she's lining up a shot and interrupt her charge with a sword strike before she shoots you, which would normally result in an instant KO.
After the third phase the running ends, and everything is confined to just one part of the arena. However, the fourth and fifth phase suffer the same problem The Scale had, as you can sit in one corner here and keep shooting at The Burst while parrying her incoming melee strikes since she doesn't really do anything else, which is a shame considering some of the other attacks at her disposal which she can't even perform anymore. At least the phases after the third one have melee phases to spice things up. What's interesting is that The Burst will taunt you into attacking as she's talking which would normally signify that the boss is vulnerable, but here it's the opposite as she will counter-attack immediately.
The final phase is probably the main contributor for why the fight is so damn challenging, as you're barraged by shockwaves from the top, left and right, while having to move behind walls to avoid incoming sniper shots. Though I don't like the dashing in Furi, it's actually fair in this phase when they aren't quick attacks you have to reflexively dodge and built around dashing being an on-button-release function. The waves have a good amount of space between them as dashing at the wrong moment will also leave you vulnerable to other waves.
The Burst is bretty gud aside from some annoyances, has the best song playing from the soundtrack too. It's largely challenging in the right aspects and the presentation is top notch, but is brought down by some core problems like the running around involved in the first three phases and the oversimplification of phase 4 and 5.
The eighth boss, (ow) The Edge, is Musashi Miyamoto redesigned by Ozaki (boat paddle included) and is a melee-only boss. While he's made up to be a giant badass, he comes over as a giant pushover since his fight can be cleared in 50 seconds. Despite this, he does take the melee phases of Furi to their extremes.
Unlike most bosses, The Edge isn't a boss you can beat by passively attacking him once his combo is over. You're expected to constantly attack him mid-combo to find the weakpoints and take him out quickly as possible. The thing is that the vulnerability states of a boss in Furi is fixed depending on what he's doing, so it kind of feels like a case of trial and error as you're poking everything trying to find the hole in his defenses. The windows of vulnerabilities are even smaller on Furier. However, as this is a melee phase, you can skip the first three phases entirely if you strike The Edge with a boost attack, as striking The Edge once with a boost attack will deplete his entire HP bar. But with a boss as aggressive as The Edge, finding the right time to boost can be difficult. But the speedrun records for The Edge involve boosting right at the start of the phase and ending the phase immediately by striking him after one parry. But if you try to do this yourself, you'll run into some problems.
