Birthday: March 2 Sign: Aquarius Blood Type: A Height: 155 cm Class: Freshman Caustic, unyielding, and quick to let her dissatisfaction be known, Tsugumi’s intolerable personality has provided few friendships; though in truth has little desire in expanding upon those she already treasures. In light of this, she is strongly protective of Maki Hoshikawa – whom she regards as a sister – and constantly fears others will take advantage of the girl’s naïveté and innocence. When away from her companion’s side, Tsugumi can be found spending time at the academy library or in attendance of literature club functions.
Birthday: September 16 Sign: Virgo Blood Type: AB Height: 164 cm Class: Freshman Introversive and dismissive of her peers, the virtuosa Rhythmy is something of an enigma. Perpetually wearing sound canceling headsets, it is unheard of for her to accept invitations or initiate interactions with others. On the exceedingly rare occasions that she deigns to fleetingly acknowledge another person, the encounter is distinctly defined by Rhythmy’s eerie silence and unemotional facial expression. Though few have managed conversation more than a single sentence with the young woman, one cannot deny her expertise as a pianist is nothing short of perfection.
Birthday: January 12 Sign: Capricorn Blood Type: O Height: 153 cm Class: Freshman With a principled competitive nature and natural aptitude to excel at an exceptional range of athletic activities, Itsuki’s direct mannerisms and masculine habits would have observers brand her as the classical embodiment of a tomboy. Though capable of mastering any sport she participates, Itsuki would readily declare that soccer is the most enjoyable and rewarding. At times her dedication can be borderline obsessive, as it is not uncommon for her to spontaneously start dribbling or perform warm-up exercises to pass idle time.
Age: 16 He always says whatever he thinks and doesn't even care if it's in public. He is a real pervert and even touched his teachers breasts, because he didn't wanted to wear the school uniform. His is one of the factors who can store powerful HI-ERO particles, but he also need to do perverted thing to Kyouko to increase his "Hi-ERO" powers when fighting.
