Arsene and Robin

Arsene and Robin are Shiro Touma's primary firearms in End War Online.

Design
Both guns are based on the H&K P30L pistol, both running 9x19mm ammunition. The two of them have been extensively modified, their most obvious modification being the secondary barrel and trigger. The designs were inspired by the handguns his father wielded during his time in Gun Gale. Modifications include:
 * 2.5 lbs competition-level short-pull trigger
 * Leupold Delta Point Pro reflex sights
 * Skeletonized hammers
 * Reconstructed frame designed to host a secondary barrel and trigger assembly for firing a lock-breaching slug
 * Titanium Nitride-coated 5.4 Inch Match-Grade Bull Barrel with porting meant to match the muzzle compensators
 * Custom-designed fire control group
 * Fiber optic sights in the event that the Reflex sights become unusable
 * Stainless Steel Guide Rod
 * Flared mag-wells for easier reloading
 * Extended ambidextrous magazine and slide releases, and safeties
 * Ergonomic handgrips with wood grips featuring synthetic inserts
 * Robin features his ejection port on the left side with all associated systems redesigned to match this, as he is meant to be used in the left hand
 * Robin features a polished chrome finish with gold engravings and his name inscribed in royal blue on the slide, while Arsene has a dark chrome finish with bright silver engravings and his name inscribed in red on the slide
 * On the other side of their slides, the guns are engraved with "For Shiro Touma, with Butterfly Kisses" in a cursive font. Each word alternates between gold and silver.
 * Custom octagonal suppressors were made for the two, with Robin's featuring white, gold, and blue engravings while Arsene features black, silver, and red.

Both Arsene and Robin are designed for stealth and lock-breaching. They are almost always equipped with their customer suppressors, sliding over the compensators and locking into place with a sliding unit that aligns on the compensators. They were designed to avoid interfering with the secondary barrels beneath, which load via a hinging joint underneath the end of the main barrel. To load the proprietary lock-breaching slugs, Shiro simply needs to swing out the secondary barrels to expose the opening, load in the slug, then return the barrel to its original position. Both are commonly loaded with 9mm Major ammunition in 15-round magazines, and the slugs are made in 12-gauge shells.

Trivia

 * The guns are influenced by his father's guns, as stated above.
 * Arsene and Robin are ironically the opposites of Dusk and Dawn. Arsene and Dawn, the right-handed guns, feature opposite color schemes, as do the left-handed guns Robin and Dusk.
 * They were made by Tokime Suginami, as her gunsmithing signature on the slides indicates.
