My second wife :)

Murokasa Akane

An agent of the Millennium's secret organization, C&C. Her codename is "zero-three", an essential employee at "cleaning up".

She is known by the nickname "Sweeper Master" for her ability to infiltrate enemy lines with a deceivingly tender impression and gracefully yet explosively "clean out" the enemy.

Akane is caring in Sensei's presence. she seems to care for Neru, but as we all know, Neru doesn't need help from anybody.

Akane also has a habit of "cleaning out" the enemy lines with explosives, much to Yuuka's chagrin.

She wears a Japanese maid outfit, but with a longer skirt with twoblue stripes on the bottom. She has long pale blonde hair. She also carries a big black box that carries what apears to be rigged TNT, or another explosive.

Story

Akane operates an F-15EX Eagle II, a dogfighting monster that has alot of Air-to-Air missiles. Even though she isn't a aggressive one but don't be fooled by her looks, her skills in engaging is quite impressive and superb. She may be careful, but she has a scary side.

F-15's irl information

The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather fighter aircraft designed by McDonnell Douglas (now part of Boeing). Following reviews of proposals, the United States Air Force (USAF) selected McDonnell Douglas's design in 1969 to meet the service's need for a dedicated air superiority fighter. The Eagle took its maiden flight in July 1972, and entered service in 1976. It is among the most successful modern fighters, with over 100 victories and no losses in aerial combat, with the majority of the kills by the Israeli Air Force.

The Eagle has been exported to many countries, including Israel, Japan, and Saudi Arabia. Although the F-15 was originally envisioned as a pure air superiority fighter, its design included a secondary ground-attack capability that was largely unused. It proved flexible enough that an improved all-weather strike derivative, the F-15E Strike Eagle, was later developed, entered service in 1989 and has been exported to several nations. Several additional F-15 variants have been produced.

The USAF had planned to replace all of its air superiority F-15s with the F-22 Raptor by the 2010s, but the severely reduced F-22 procurement forced the service to operate some F-15C/Ds until 2026 and replace them with newly built F-15EX Eagle II in order to retain an adequate number of air superiority fighters. The F-15E Strike Eagle is expected to continue operating in the USAF into the 2030s. The F-15 is in service with numerous countries, with production of enhanced variants ongoing.
