Kyuu - The unusual main protagonist of the game from Detective Academy Q (also called Detective School Q or Tantei Gakuen Q) who found the titular storybook. He's a bit hyperactive, socially awkward, and childish at times, but he's actually very intelligent once he gets serious. Unfortunately, he is very weak due to his lack of experience in combat, so he needs to rely on his new friends while training to become stronger. To make up for his painful weakness, his deductive skills are absolutely amazing for a junior detective and he has a hidden talent of leadership. After finding it wrong to live in a world of fantasy, he goes on a journey to find the way back home while solving the mysteries surrounding the storybook.
Kite- The deuteragonist of the game and the main character from the original .hack games. As the very first character who joins Kyuu, Kite acts the second-in-command of the party. While Kite is a potential leader, he strongly supports Kyuu sharing a brotherly friendship and usually acts as the voice of reason. Kite is both strong, fast, and capable to use a few basic spells, which makes him one of the most valuable allies. His weapon is a pair of blades.
Dark Magician Girl- The tritagonist of the game and one of the famous characters from Yu-Gi-Oh! (she is not related to the anime or manga series) A magician-in-training, she's the second to join Kyuu's party. She is a Duel Monster spirit and gets constantly mistaken as a human girl due to her appearance. She shares another strong friendship with Kyuu and Kite. Although, unlike Kite, she gets very annoyed by Kyuu's childish antics. She knows a lot about magic spells though she's still learning them and her capability as a Black Mage makes her another valuable ally. Her weapon is a magic wand.
Sakura Kasugano- The hyperactive, fight-loving character from Street Fighter. She is one of the main characters and also one of the first to join the party. Sakura recently moved into the Cyril Region where she makes friends with Kite and the others. She is known as the 'Ditto Fighter' due to her ability to use skills that most fighters use such as a Hadouken though it's self-taught. Her main weapon is her fists, but she can also use some gauntlets and brass knuckles.
Kanata Saionji- The 'handsome, pretty boy' and main male lead of his series, Daa! Daa! Daa! (or also known as UFO Baby). He is quite popular with the girls due to his good looks and attitude. Not only does he excel in his studies, he is also good at sports. Apparently, he comes from a line of Buddhist monks until he moves into the Cyril Region where he befriends Kite and the others. He may initially appear as a Deadpan Snarker, but deep down, he's a kind, caring person. Among the first members of the party, Kanata is the 'jack-of-all-trades,' as he masters the basic sword skills (his main weapon is a katana.)
Nina Sakura- a kind-hearted, very peppy, and perky character from Ultra Maniac. She is actually a magic girl (or a witch) who comes from a kingdom in another region. However, she proves to be a failure as her magic usually backfires save for a few white magic spells. As a result, she's sent to the Nutsy Guild as part of her training to improve her magic. She'll do absolutely anything to ensure that her friends are happy, even if it means suffering a little grief herself. Nina is the healer of the group. Her main weapon is a magic staff.
Noel Vermillion- A shy, clumsy girl who tends to get worked up over the smallest things. She can be socially awkward at times, but this has actually served as an endearing trait. She quickly becomes close friends with the first members of the party, but it turns out that she already knows Kite and Kanon. In fact, the three of them are close friends. She is the 'Glass Cannon' of the group as a professional gunslinger capable of delivering critical damages on the enemies. Her weapon is a pair of handguns.
Kanon- A mysterious young boy from Umineko no Naku Koro Ni (means When the Seagulls Cry). He appears to be sullen and quiet, usually doing his work in silence. He doesn't talk much either though he does voices his opinion during a discussion whenever he wants to. Apparently, he knows Kite and Noel for a long before meeting Kyuu and the others. There have been rumors that they're close friends as well. Kanon is supposedly the strongest among the first members of the brigade, known as the 'Lightning Bruiser.' His main weapons are a two-handed sword and a latex scimitar.
