In her final moments alive, Hinako is shown thanking Rio Ranger after realizing he had a part in her death, revealing that she had wanted to die.

Hinako has a blunt way of speaking and somewhat of a fatalist mindset; stating "there's no way to deal with this" in the face of Hayasaka's near-death. Remarked by Gin to be "kinda violent", Hinako easily comes up with solutions for fighting the monsters they encounter, and always offers to fight whatever's in the group's way.

She is rather strategic and thinks before speaking; stating her means of defense against the Death Game is keeping the information she has to herself, for the time being, not wanting to be used by the others.

However, despite her analytical behavior, Hinako is also shown to be slightly different from her human form. She wants to survive and is quick to get on to the other dolls when they insist on helping the survivors, evident when the others try to stop Q-taro from bleeding. She is also quite judgemental and aggravated in the Shin Survives route when Ranmaru decides to be "it" for Sara. As well, during the battle with Midori, she actively stops participants from attacking him, such as grabbing on to Gin's shovel or knocking the gun from Keiji if he tries to shoot, which further proves her desire to live.
