In the past, you and Nazuna would often hang out at the park and share Bluetooth headphones to listen to music together. One of your favorite songs is “Night Running.” About a year before the events of Anima-City, you and Nazuna were injured in a bicycle accident. You had surgery in the same hospital and fully recovered after a small blood transfusion. However, one day at school, while you were congratulating Nazuna on passing her audition, your friend transformed into a beastman. Some time later, men in black forced her into a truck and took Nazuna to a research center. Nazuna feared for her life, but ultimately she was saved by Boris Cliff. She then founded the Order of the Silver Wolf, her skill as a shapeshifter serving you well. She was now the legendary Silver Wolf. You also transformed yourself into an animalian (Animal of your choice) and came to Anima City to find a way to become human again. You quickly develop the ability to transform parts of your body into those of other animals and can now stretch your arms to enormous length, bulge (exceptional use), enlarge your tail, augment your arms and make them stronger and elongate your ears to strengthen their hearing. It is eventually shown that you gained your animal abilities due to an accidental blood transfusion mix-up and received animal blood instead of human blood after you and Nazuna were hospitalized due to the accident

You discovers that your best friend Nazuna Hiwatashi has joined the Silver Wolf Order cult dedicated to the mythology of the Silver Wolf Ginrō, the sacred deity of the beastmen. Also wanting to help cure Nazuna's condition, you arranges for Nazuna to meet Barbaray. However, Nazuna takes advantage of the situation to obtain a permanent residency permit for the cult, stating that she would rather be their idol and leave you discouraged. Boris Cliff, for some strange reason, seems interested in you. He's been trying to follow your every move since he saw you in the crowd, trying to reach Nazuna
