The KIDDY GiRL-AND official site database has (finally) been updated with information on some of the new characters
Di-air - 7-year-old companion of Ascoeur and Q-feuille and ES-member apprentice apprentice. Her special ability is called "A-quare" (エイ・キュア ei kyua)
T.A.M.A - stands for "Trial-type of Assemble-system & Multipurpose Automata", a Gene-tec beast that can transform into anything. A mascot character usually disguised as Di-air's pochette until transformed by her kiss.
Trixie - Ascoeur's sempai and one of the strongest ES-members, a cheerful older sister-type adored by everyone. Her ability "Power-S" (パワーズ Pawaazu) allows her to manipulate space.
Troisienne - Trixie's partner and one of the strongest ES-members. Mature and gentle but with an unexpected childish side, her ability "Particle-T" (パーティクレットpaatikuretto) allows her to manipulate time.
