Another entry in the long list in the {{Harem|Genre}} genre. The story follows Taiga, [[BlatantLies an ordinary high school student]], and his [[HumanAlien sister]] [[InnocentFanServiceGirl Tubame]]. Taiga cannot remember anything up to a few years ago and relies on Tubame to take care of him after an accident that he cannot remember killed their parents.

!!This manga provides examples of:

* BewareTheNiceOnes: Taiga. Holy ''Shit'' is he ever this trope. For the first few chapters he comes across as sweet-natured LivingMacGuffin who has to rely on Tubame to protect him from Phantoms. Then in chapter 12 he gets cornered by a rampaging Phantom, which prompts [[SuperpoweredEvilSide ''another'', much more dangerous Taiga]] to come out and play. We don't see what happens next, but when Tubame and Ura finally bust their way into the room, they find a very tired and confused Taiga propped up against what's left of the Phantom after ''something'' ripped it to shreds.
* ClothingDamage: Often.
* EldritchAbomination: The Phantoms.
* {{Fanservice}}: UnwantedHarem. Need we say more?
* ImmodestOrgasm: Tubame is clearly having one in the final chapter, which may be partly caused by Taiga being the remains of a silicon based LivingRelic which can make use of ThePowerOfCreation...even for doing "that" with her.
* SleepModeSize: Ura put herself into this when she gave up being a space pirate after living with a family on Earth.
