Evolver

The **Exciting VOLtaic VERsatile Gun** (勵磁電流式多目的銃), also known as the **Evolver**, is a weapon featured in both *AI: THE SOMNIUM FILES* and *AI: THE SOMNIUM FILES - nirvanA Initiative*.

Initially, the Evolver was Kaname Date's gun, issued and developed by the Advanced Brain Investigation Squad during the 2020s. By 2030, the Evolver had become standard issue for ABIS agents, with one being given to the new recruit Kuruto Ryuki. It is capable of firing a variety of bullet types.

## Design

The Evolver is designed similarly to a revolver, with a single barrel and a six-chamber cylinder. Its barrel has a futuristic design, with the inner workings of the barrel exposed to show the neon blue electromagnetic power that the Evolver employs. Because it uses electromagnetic force, the Evolver is capable of firing multiple different types of bullets.

### Live rounds

**Live rounds** (実弾) are regular bullets, only deployed when lethal force is required.

* In *nirvanA Initiative*:
	+ In "2/14 Mizuki Chapter 4 M1 - In Truth", Date uses two live rounds to shoot at Tearer when he has a gun aimed at Bibi's head. The first bullet knocks the gun out of his hand while the second ricochets off his mask, causing half of it to break off.
	+ In "2/15 Ryuki Chapter 5 R1 - She Was the Universe", Ryuki loads the Evolver with live rounds at Tama's command while facing off against Tearer at the Naix Cathedral . However, he is unable to shoot because Tearer possesses a dead man's switch.
	+ In "2/15 Mizuki Chapter 5 M1 - The End of Craving", Date switches from stun rounds to live rounds after the former prove ineffective against the enemy at Tokyo National Stadium. However, he does not use them to kill, instead shooting his opponents in their arms and legs to incapacitate them.

### Explosive rounds

**Explosive rounds** (炸裂弾), also known as **burst rounds** or **scattershot rounds**, are bullets with a fragmented tip. When they are shot, there is a small delay before the fragments explode out.

* In *SOMNIUM FILES*:
	+ In "Day 3: Sunday -syokubAI-", Date uses an explosive round while facing off against Chinpei Wagai and Dokuta Yogano in the Kumakura Office. He shoots it at the golden ball that one of the dragon statues holds, which causes the ball to explode and knock out Chinpei and Dokuta with its fragments.
	+ In "Day 4: Monday -syuurAI-", Date uses an explosive round while facing off against the foreign mercenaries at Golden Yokocho. Aiba commands him to shoot the bullet at a porno mag vending machine, which causes it to explode and send porno mags flying everywhere, distracting the enemy for Date to make his next move.

### Stun rounds

**Stun rounds** (スタン弾) are presumably the bullets that are shaped like a taser, with a wrapped coil leading to a small prong. When they are fired, they release an electrical current through the object that is hit.

* In *nirvanA Initiative*:
	+ In "2/14 Mizuki Chapter 4 M1 - Visions", Ryuki is blackmailed by Tearer and forced to shoot Bibi with a stun round. This sends an electrical current surging through her, knocking her to the ground and short-circuiting Aiba. This also has the unintended side effect of making Bibi's weak heart even worse, leading her to harbor a grudge against Ryuki.
	+ In "2/15 Ryuki Chapter 5 R1 - She Was the Universe", Date and Ryuki use stun rounds when facing off against the members of Naix at the Cathedral.
	+ In "2/15 Mizuki Chapter 5 M1 - The End of Craving", Date initially uses stun rounds when facing off against the large group of enemies at the Stadium. However, the enemy wore insulated suits that protected them from the electrical shock, so Date switched to live rounds instead.

### Stun grenade rounds

**Stun grenade rounds** (スタングレネード弾) are bullets that, as their name suggests, are shaped like a small flashbang. Firing them will release a blinding light that stuns anyone within the immediate vicinity.

While Date and Ryuki have not been seen using stun grenade rounds, Mizuki has used them with the Evolver MC.

### Anesthetic rounds

**Anesthetic rounds** (麻酔弾) are bullets armed with a small syringe. Shooting them will inject the object with a powerful anesthetic, enough to knock out a grown man for 12 hours.

* In *nirvanA Initiative*:
	+ In "2/14 Mizuki Chapter 4 M1 - Visions", Date arrives at the Kabasaki Chemical Plant where Bibi is at the mercy of Tearer. He immediately shoots Tearer upon spotting him, injecting an anesthetic into his chest that knocks him out for long enough to be Psynced into.

### Wire rounds

**Wire rounds** (ワイヤー弾) are bullets with a grappling hook and wire. Shooting them will launch the grappling hook, which can then presumably be used to latch onto faraway objects.

* In *SOMNIUM FILES*:
	+ In "Day 5: Tuesday -seisAI-", Date is commanded by Aiba to fire a wire round directly into the sky. By doing so, the hook and wire serve as a lightning rod. Date then throws the Evolver into the pond at the Sejima Residence where the enemy are charging into, causing them all to get electrocuted and knocked out when the lightning strikes.

### Spherical rounds

**Spherical rounds** (球形弾) are bullets that are spherical rather than cylindrical. They also appear to lack a casing like other bullets.

* In *SOMNIUM FILES*:
	+ In "Day 5: Tuesday -seisAI-", So Sejima holds Mizuki hostage, preventing Date from shooting at him. Instead, Date throws Mizuki's pipe outside of the residence and shoots a spherical bullet at such an angle that it enters the pipe, exits out of the other end, and manages to hit So from behind.

### Firebomb rounds

**Firebomb rounds** (火炎弾) are bullets with a red tip as opposed to the regular bronze one. Firing them produces a stream of flames behind the bullet.

* In *SOMNIUM FILES*:
	+ In "Day 5: Tuesday -jinnAI-", Date is confronted by Boss and a group of SAT members at the Sagan Residence. Aiba commands Date to throw flour into the air, then shoot off a firebomb round that causes a dust explosion, knocking out Boss and the SAT.

### Unknown bullet

The bullet selection screen for the Evolver in *nirvanA Initiative* features a bullet in a light blue coating. This can be presumed to be some sort of **rubber bullet**, but it is not explicitly identified or used.

### Unspecified

Moments in the series where the exact type of bullet used is not specified or is otherwise unclear:

* In *nirvanA Initiative*:
	+ In "2/13 Ryuki Chapter 3 R2 - Joy for Anguish", Ryuki confronts a group of Horadori researchers at the Harbor Warehouse District. He fires rounds from his Evolver which incapacitate the enemy, but it's unclear whether they are supposed to be stun rounds, live rounds, or something else.
	+ In "2/15 Mizuki Chapter 5 M1 - The End of Craving", Ryuki arrives at the Stadium and saves Mizuki by shooting at the three men who have her at gunpoint. Date switched from stun rounds to live rounds beforehand since the former were ineffective at keeping the enemy down - however, this was before Ryuki arrived at the Stadium, so it is unclear whether Ryuki had also switched to live rounds or was still using stun.

## Trivia

* The spherical round is the only type of bullet that does not make a return in *nirvanA Initiative*.
* In New Investigation, there is an unused line where Aiba remarks that Ryuki's Evolver does not smell of gunpowder, a sign that it is fake. Presumably this was removed since Evolvers do not operate like regular firearms, and may not use gunpowder at all.
