★Cless-kun
The main hero versus the heart-felt witch... It's obvious that in the beginning, Arche had a thing for Cless. She thinks that valiant swordsmen in tights is sexy... okay, maybe not just that. In the ever-famous boat scene, Arche's curiousity peeks her to drink some wine. Arche literally ends up waking up in and out from a drunken dream of Cless hitting on her/having sexual intercourse with her. When venturing the Tower of Twelve Stars, a fairy blackmails Cless to kiss Arche in order to proceed. Although the plan didn't suceed, Arche was very excited at the thought. The wedding scene for Elwin and Nancy ends with a them offering gloves to Mint for her help, telling her that she was next. Arche later then tells that she wanted to get married, then jumps the question on Cless. In all, she was kidding... In the Arena, Arche goes screaming Cless's name out of compliments before his matches. However, her love for him is more teasing-like. It seems like she really knows that Mint has feelings for him. She likes to poke him with ideas of love, but later on telling him that they were all a joke. Throughout the rest of the game, Arche constantly tries to play cupid for him and Mint, telling him to commit to her once in a while. Her feelings for him died soon after, since she knew it was impossible to try to win his heart, but she still cares for him deeply, willingly to aid him no matter what, but just as good friends.
★Baka
The hero's best friend versus the heart-felt witch... Without a doubt, one of the official couples of the game. They possess a strong love-hate relationship. Arche thinks Chester got good looks, but she dislikes his wannabe-ways on trying to be good enough for the group, especially since he hasn't gain any levels throughout the years. To this remark, Chester dislikes Arche for putting down, and soon a throw of wits between the two started. But there is love deep within the elements... its just hard to find any of those. Arche is the only person who bothers to tell Chester the whereabouts of the gang beforehand, and when not pissing each other off, talk to each other by themselves. In the OAV, Arche actually worries about Chester than just teasing him like in the game. However, in the end of the game, Chester tells Arche how much she means to him before she departs back into the past. Since Arche is a half-elf, she waits constantly for him ever since, wonder as the years past if she ever would be able to tease him again. Even in the Drama CDs, it has been mentioned of their love.
★Mint-chan
There is no sign of any love between Mint and Arche, but many yuri fans love to put them together. I find it hard, since these two don't interact much. Arche seems to treat Mint as a dear friend, since she is the only girl in the group aside herself, and without Suzu yet. During the Elven Bow sidequest, Arche risked her life to turn to stone in order to prevent Mint from doing the same to have Chester's Bow repaired. They have some "girl talk" as the guys like to put it. They are able to interact with each other, and feel gentle than compared to the boys. There is no sign of jealousy with Mint having feelings for Cless, in fact, Arche loves to play match-maker with the two later on, constantly bothering Cless to try to commit to Mint. However, there are slight cases in which Mint can be resented to Arche, most often when she tries to hit on Cless, like asking him to marry her or awaiting a kiss from him, making Mint flustered and often try to pull Cless back from the judgments. Arche does have one jealously peak... Mint's figure. She loves to have her breast measurements anytime!
★Klarth-sensei
While Arche likes postivity, Klarth likes to keep things serious and to the point. Klarth and Arche hardly interact, but they find themselves somewhat similar. They both can use magic to attack their foes, they are both from the past world, and they like to poke at each other. Arche disrespects Klarth like an old man, but she always refers to him as a teacher, most likely for his scholar status. Klarth, at first, thought about going out with her, but was shunned by Cless reminding him of his own love at home, Mirald. Klarth likes to insult her intelligence at times, like in the Morlia Gallery when Arche tried to read the stone tablet. Despite his attitude, Arche always manages to tolerate him, even when he acts smart-mouth toward the group.
★Suzu-chan
Suzu and Arche hardly have any type of interaction. Suzu is cold, silent, and basically a taciturn, while Arche is the complete opposite. Arche does pity Suzu and her past, and tries to help shape her life to less depression from her ninja training.
★Dhaos
Dhaos and Arche have no relationship. Even though Dhaos was the one responsible for Demitel's murder over her good friend, Ria, Arche hardly felt any rage toward him. In fact, she even questioned what was his purpose in doing his actions and what hope the group has to accomplish this. She objected to take the risk into immediate extermination of him. It was the death of Edward D. Morrison by one of his minions that forced Arche to become his enemy.
