Kaguya

Kaguya was an advanced experimental weapon developed to fight the super-large Houkai beast undergoes self-apoptosis every 15 days, and then regenerates as a new individual based on the internal core. Although there will be no changes in appearance, weight, and height, it can be judged that each is a different individual. Based on the characteristic of being able to regenerate continuously, it can be regarded as a one-man army in a sense.

As a synthetic girl developed secretly by Anti-Entropy, Kaguya sighs that her life is fragile and short, and she treats her limited daily life with sentimentality. If it hadn't been for the beauty of the relationship between Bronya and others at the end, and the friendship she wanted to pursue, Kaguya might not be able to let her go at the end of her life and head towards the end with satisfaction.

Main story

On a crescent night, Kiana and her team encountered a huge cabin. After opening it, she met Kaguya. After being awakened, Kaguya failed to connect to the Anti-Entropy network system, but still activated the Valkyrie System with her consciousness, and fought Kiana and her group for the first time, and was repelled. For the first time, Bronya identified this as a failed Anti-Entropy experiment and found that it was a failed operation, with only 360 hours of life maintenance time.

At the time of the third day of the moon, Kiana and her party once again found Kaguya who was following. Kaguya created a firefly-type drone this time and lamented the short and perishable life of fireflies. After Raiden Mei retorted, she showed her willingness to find a friend, and then said, "Bronya, die with me." And shot again. Before leaving this time, Kaguya said that she would take Bronya to her next meeting.

Finally, at the time of the full moon, Kaguya reappeared and grew to a certain extent. Her hair became longer. Like a legendary witch, her feelings were also influenced by jealousy. After sorrowing for her destiny, she expressed her desire to be with Bronya. Bronya and the others played a game to prove their value as weapons.

After fighting desperately, the body controlled by Kaguya was completely silent, and its life came to an end. After being satisfied, Kaguya dissipated under the full moon.

Wonderland

As a servant, she met Chloe after resurrected at the Wonderland continent. The two lived together. Although they had conflicts at first, they became unable to leave each other after experiencing various things.

After the battle between the Hyperion and the Moonlight Throne, because Chloe was forcibly taken away by the Moonlight Throne, Kaguya didn't want to participate in the battle and had to join the Hyperion faction to find Chloe.

During the War of the Ancients, because Chloe was out, Kaguya ignored the Hairball who invited her but sent them to deliver letters to Chloe.
