Koharu

Student, young hostess from DOA Venus vocation Koharu (Japanese: 小春) is a young student and aspiring Ryokan hostess, who appeared in the November 2, 2021 update for Dead or Alive Xtreme Venus Vacation in the DMM and Japanese Steam versions, and the November 24, 2022 update in the Johren and Singapore Steam versions.

She was the daughter of a couple who owned a Ryokan (traditional Japanese hot spring inn). In large part because of this, she aspired to become a hostess of her own inn. While growing up, during her breaks, she often went to the relaxation room and read various books inside, which contributed massively to her later love of classical Japanese literature. She also learned scant details about stargazing at a school event, which until her arrival at the Venus Islands was the closest she had to any experience with the activity.

She eventually went to the Venus Islands to work at the hotel (and presumably also the then-recently constructed onsen), as a way to ensure she completed the necessary training to become a hostess due to feeling training at her parents' inn would only have her go too easy on herself. While trying to get her luggage to the hotel, she stumbled and fell on the Owner. Afterwards, the Owner decided to have her be a participant in the Venus Festival.

Koharu has pale skin, black hair worn in a side ponytail held by a pink string with a gold jingle bell, and purple eyes. She is not as busty as the other girls, but still possesses an ample chest. Her main attire, Hospitable Beauty, is a slightly revealing kimono, similar in overall appearance to the Stylish Blossom outfits, albeit with yellow mixed in. Her belt buckle has a stylized owl on it. It also included an apron, which according to Koharu had been made by her mom shortly before she left for the Venus Islands. Although nowhere near as short as Marie Rose or Kanna, she is nevertheless one of the smaller girls on the island.

Owing to her desired career choice, Koharu was shown to be meek, dutiful, and submissive. She also utilized respectful terms towards the Owner and to a lesser degree the other Venuses (initially referring to the latter party by the suffix "-Sama" in the Japanese version and the pronoun "Ms." in the English localization until Leifang told her such wasn't necessary). Similar to Marie Rose and Patty in the Japanese version, she at times refers to herself in the third person, although not nearly to the same extent. This trait likewise is toned down in English localizations. She also has some degree of insecurities about herself and whether she'll succeed at being a good innkeeper, even deliberately going to the island to ensure she doesn't "go easy on [herself]," and also tending to lament whenever she makes any failures to her training and get apologetic. Partly because of her insecurities, she also tended to get reckless to her own well-being to ensure she does a good job, a notable instance of this is when she overworked cleaning the onsen and ended up becoming unwell enough that she passed out with a significant fever and had to be confined to a bed.

Koharu idolizes her mother, with her specifically wishing to become an innkeeper to emulate her mother. When she was much younger, she often tended to place her head on her mother's lap while napping, an action that she eventually repeated with the Owner years later. Her mother later sent a letter to Koharu giving some encouragement, as well as advice about how she needs to keep a relaxed attitude to make her guests at ease while also adding she missed her daughter. Koharu when reading that last bit also speculated that she may have inherited her clingy attitude from her mother.

Koharu met Hitomi as well as Leifang in person shortly after the latter party did three laps around the island. However, she already knew their names and faces by that time by having studied up on them, citing that as being an important skillset for acting as a landlady of an inn someday. Hitomi also related somewhat towards her desire to train in innkeeping, due to her constantly training her Karate skills even during vacations. She also offered to have Koharu train alongside her, although she refused, mostly because her job didn't allow for that kind of training. She also watched with some amusement Hitomi and Leifang get into an argument over cooking, glad to gain some "older sisters."

Leifang also told her not to be so formal with her fellow venuses when she initially addressed them with "-Sama" (localized as her addressing them with "Ms."), with her taking Leifang's advice to heart. Leifang also offered to teach Koharu how to prepare Chinese dishes, with Koharu agreeing mostly because the hot spring inn that her family owned was also getting foreign customers and thus knowledge on foreign as well as Japanese cuisines will ultimately be necessary in the near future. She also watched with some amusement Leifang and Hitomi's argument after the latter implied that Leifang tended to add too much spice, as well as expressed gladness at gaining "older sisters."

Misaki apparently met Koharu the first day of her arrival, and even provided pointers to her regarding working with the Owner, based on statements made by Koharu in one of her debut episodes. Misaki largely related to her due to her also working part time for the Owner as his supporter. The next day, Misaki learned that Koharu intended to clean Tamaki's room, but she was not responding (due to her sleeping past noon), which ultimately culminated in Misaki having to break into her room to allow Koharu to clean it.

During a stargazing festival, Koharu alongside Elise tried to get aid from Misaki regarding how to Stargaze due to her expertise in the field (as neither of them knew how to do so due to little to no actual experience in doing the activity before then, Koharu in particular having only had second-hand knowledge on the subject via a school event in her past). Misaki then gave them some advice regarding knowledge on stars and constellations, as well as it not requiring deep thoughts and "the most important" part about it before getting back to work.

Ayane, alongside Fiona, met Koharu in order to thank her for opening up the onsen. Ayane remarked it "wasn't bad", and admitted that, although having more experience in the area than Fiona, she didn't generally participate in them. After learning that Koharu was working the same time that the onsens were open, she asked her if there was another means to interact besides that. Ayane reluctantly participated in the pajama party afterwards. She also learned of Koharu's love of classical Japanese literature, and admitted that, Tale of Genji aside, she wasn't familiar with many books in that genre, with Ayane giving more cynical commentary after Koharu explained what that story was about. Specifically, she considered the eponymous character to be a womanizer, though she nevertheless expressed some grudging respect for him actually being loyal to his lovers.
