- Anti-Climax Boss: Spiritual Larsa in Futari Black Label's God mode, believe it or not. While she is still of course the game's ultimate challenge and she gets a far more dramatic presenation than her Ultra mode counterpart (which simply reuses the standard boss BGM and doesn't involve her crossing the Bishoujo Line), she is overall easier and her final phase actually has safespots; she summons a circle of pods that release bullets and with some careful maneuvering, you can stay between two of the pods as they move and never get hit. This was not fixed in the 360 port.
- Awesome Music: Composed by shmup soundtrack legend Manabu Namiki, as well as Masaharu Iwata (composer of soundtracks for SoulCalibur IV, Final Fantasy XII, among others) and Kimihiro Abe for the sequel. There's also the Double Arrange album which re-arranges the tracks from both games through a variety of other famous composers.
- To Shinju Forest is an awesome kick-starter. Here's the version composed in the double arrange album, or another album here.
- While Furthermore, Cross the Desert Too is nice, the arrange album version? Composed by none other than Shinji Hosoe.
- Like A Night of Shooting/Falling Stars is one of the most hypnotic and soothing tracks in any game, of any genre, ever. Here's the arrange album version.
- The One Who Is Always In The Forest AKA The Direction to the Heart of the Forest pumps you full of enough energy to face the final stage. Thus, here's the arrange album version.
- Here's Sea of Frozen Crystals from Futari. Believe it or not, the arranged version is composed by the one and only Youko Shimomura herself.
- Speaking of the prior final stage theme, there's also On The Verge Of Madness, which packs some oddly upbeat Chinese instrumentals but may be enough for you to take on Queen Larsa to stop her once and for all. For any Armored Core fans (and the despite the lack of the prior Chinese instrumentals), Kota Hoshino did the arranged version.
- The final boss theme of the same sequel? Cry! Scream!, as aptly named. Arranged version by Ayako Sasou here.
- Complacent Gaming Syndrome: Most players regard God Mode as the only thing worth playing in Futari Black Label.
- Contested Sequel: Well, Contested Expansion Pack: Futari Black Label.
- Even Better Sequel: Futari.
- Funny Moments:
"This game is for use on Earth and by Earthian only. Sales, export, or operation outside this planet and/or to the extraterrestrials may be construed as copyright and trademark infringement. Violators are subject to severe penalties and will be prosecuted to the full extent of the jam."
- The legal warning on the original game said that it was for use in Japan only and exporting to other countries would be illegal. The warning on the Steam version, on the other hand...
- Good Bad Bugs: The "counter banking" technique in the original game, allows you to get much higher scores than intended in Maniac and Ultra modes.
- It's Easy, So It Sucks!:
- Averted with Futari Novice; many players regard it as well-designed and as an opportunity for non-shmup players to get into the genre.
- On the other hand, played straight with Futari Black Label's Original and Maniac modes.
- Memetic Badass: Queen Larsa, due to her status as Futari's notorious Final Boss, especially on Ultra difficulty where she has a True Final Boss form and becomes known as "THE HARDEST VIDEO GAME BOSS EVER".
- Memetic Mutation: "THE HARDEST VIDEO GAME BOSS EVER!"Explanation
- Moral Event Horizon: In Futari, Queen Larsa goes batshit after her son dies in the previous game. Understandable by villain standards. She also decides to send her remaining child Palm out to die, dismissing him as someone she can replace anyway.
- Most Annoying Sound: Palm players will have "RECO-CHAAAAAAAAAAANNNNN!!" drilled into their heads long after they stop playing.
- Nightmare Fuel: Queen Larsa, who's basically inverse Adult Fear. Her older son Aki dies and she threatens to kill Reco, who she hold responsible for his death. What does she do to Palm, her younger son, when he tries to convince her that Reco did nothing wrong? Disown him and leave him to be killed by her forces. When he comes back to confront his mother, she attempts to kill him with the same amount of firepower she would use on Reco; in other words, she thinks so poorly of her son that to her, he's simply another bit of opposition who needs to die.
- Porting Disaster: The PS2 port, handled by Cave itself, doesn't emulate the arcade version's slowdown properly, and the game is downscaled in screen resolution, causing it to look blurry when played with the game window oriented vertically to fill the screen. The Steam port, as of this writing, is also plagued by a number of irritating (but not game-breaking) bugs, which CAVE has assured players that they will soon patch.
- Signature Scene: Much like with other CAVE games, the True Final Bosses — Aki in Mushihime-sama, Larsa in Futari, Queen Larsa in Futari Black Label — are this. Incidentally, Spiritual Larsa is better known than her Futari Ultra incarnation despite being easier due to her more grandiose presentation, her dramatic makeover, and the unique BGM she gets (In Futari Ultra, Larsa's final form BGM is simply the standard boss BGM).
- Surprisingly Improved Sequel — Mushihime-sama was interesting for its different premise and music, but otherwise had rather simple gameplay and visuals, especially compared to other Cave games. In some ways it was even simpler than DonPachi. Then Mushihime-sama Futari came along, turned the music Up to Eleven, made big improvements to the gameplay, and is considered to be one of the prettiest Cave games of all time.
- Tier-Induced Scrappy: Almost no one uses Reco-Abnormal, and for good reason—her shots are difficult to master, and her speed when using her focus shot is faster than her normal speed, in a defiance of usual Bullet Hell conventions.
YMMV / Mushihime-sama
