Hardy (ハーディ Hādi) is the goddess of the underworld and ruler of hell. Her apostle is Giselle and her shrine is Belnago Shrine.
Hardy is first brought up when Rory shows fear of riding the Tokyo subway during her first visit to Earth, when she reveals that Hardy has asked for her hand in marriage. Hardy is the one who opened the gate in Japan. Her primary reason for opening the Gate can be summed up as "Because she wants something new in her world that will likely get her interest piqued". Another reason is to destroy the old system of the Empire by making them facing enemy far more powerful than them indicating that she aware of the tremendous military power of JSDF over the Empire. She also doubts that Gisele can beat the JSDF showing that she takes the military power of the JSDF seriously unlike Zorzal and his pro-war supporters.
Despite being worshiped by most mortals in the Special Region, she is shown to be neglect and indifferent with their pledge and suffering since she cares mostly for her own interests. Furthermore, she also believes strongly in the philosophy in natural selection in which she decided to look the other way when the Flame Dragon massacred hundreds of people because she viewed it just a powerful tool for her to destroy the Gate to prevent calamity of space-time continuum as well as destroying the JSDF to maintain the balance of the underworld since the Flame Dragon is the only powerful thing in the Special Region that can give some troubles to the JSDF. To her, human sufferings and activities are just mere entertainment. As the result of her heartless and selfish approach to her subjects, Yao and the rest of the Dark Elves, formerly her ardent worshippers, have since disowned her.
She was surprised and amazed but also shocked to see that a human like Itami could defeat the Flame Dragon. This causing her to realize that the JSDF is far more powerful than she initially thought. Furthermore, she is also interest in the world beyond the gate in which she finds an amusing fact that the Earth has multiple gods for different fields like Music, Wisdom or War. However, much to her dismay, she realize that none of the underworld gods from beyond the gate are matched for her taste since most of them are male (Yama, Hades, Anubis) and she even calls one of them ugly, especially Anubis due to his dog-like appearance. However, she eventually falls in love with Aphrodite, Greek God of Love and Beauty, to the point that she makes Itami to promise her a trip to the world beyond the Gate; much to Itami's dismay since he not even sure these deities really exist or not and the knowledge of them only come from the book of Earth mythology owned by Lelei.
- Despite acknowledging the JSDF's immensely superior power over the Empire, she knows nothing about the JSDF's full power and the devastatingly advanced technology beyond the Gate as she confident that the Flame Dragon would drive the JSDF out, only to find, much to her deep shock that it was killed by Itami's C4. This shows that Gods in Special Region have little to no knowledge about Earth.
- Rory Mercury stated that Hardy was reckless and stupid for opening the Gate to Japan as her action has great potential in causing imbalance to the Special Region due to JSDF's advanced technology in disrupting the will of the Gods in stagnating the level of technology in their world. Another reason is that she afraid that she cannot stop the JSDF if they go serious on Apostles like her and wreak havoc in Special Region.
