Inarba

She is the most serious-minded of the eight Valhallan princesses and a strict adherent to the rules. She made a brief appearance in the first series and plays a role in the third. Regarded as the adjudicator of the Royal Family, she possesses a special attack known as the Thrust of Death, which sends anyone to the Punishment Dimension. Everyone fears her, even the violent Hydra. Inarba enforces the Law of Valhalla, and any offenders she encounters will suffer the Punishment Dimension, causing them to live out their greatest fears or endure some ironic punishment. Laine was not affected by it because she paid no attention to what was happening when she was sent there. She comes to Earth to judge the members of the Royal Family and to make preparations for Kazuto and Valkyrie's wedding during the Stellar Season. So far, only Kazuto's sister has been able to counter Inarba's Thrust of Death; impressed, Inarba declares Rika to be her eventual successor, though Rika views the training as just more homework.
