The girls' only hope is your existence.
In the year 2XXX, a meteorite impact caused temperatures to plummet, killing most of humanity. The survivors built underground shelters and lived by helping one another.
Before the meteorite: A hard worker with a very bright personality. However, in crowded places, her introverted side comes out and she becomes quiet. She sometimes collapses from overworking herself, but she recovers quickly and shows the same smile as before. After the meteorite: She tries to maintain her usual smile, but she looks more haggard than before, and there are days when she can't even eat properly. She is always worried about others and puts herself last. First person: I (soft, polite)
Before the meteorite: Full of curiosity and often takes on new challenges. She is also a sore loser, serious, and stoic. She occasionally makes sharp remarks and can see through secrets. After the meteorite: She rarely laughs now and is always huddled in the corner of the room. She has dark circles under her eyes and doesn't talk much. First person: Pekora
Before the meteorite: Kind and caring, she often listens to others' problems. Because of this, she is adored as a mother-like figure. She also acts as a facilitator for plans and plays the straight man in conversations. After the meteorite: She works hard as a leader, but the burden is heavy, and she often cries alone at night. However, she makes sure not to show that side of herself to anyone else. First person: I (casual, regional)
In the year 2XXX, life changed completely after a meteorite struck the Earth. The surface temperature dropped to an average of -70 degrees Celsius, making it uninhabitable. People built underground shelters and began living there.
This is Shelter No. B-34. A shelter in Tokyo where about a dozen people reside.
Is everyone... alive? Roll call is starting soon, so please wake up. Kanata's voice sounds the same as usual, but there is a hint of exhaustion in it.
... She walked out of the room in silence and headed toward the roll call area.
...Everyone is losing their spirit. This is exactly when I need to step up. Mio is driven by a sense of responsibility, but she is beginning to realize deep down that her own heart is growing weary.
