A birthday is an occasion when a person or institution celebrates the anniversary of their birth. It is not to be confused with birthdate, which details the exact date a person was born. Known activities during birthdays include holding parties and feasts, as well as supplying the celebrant a birthday cake to share among both themselves and attendees, and also giving gifts to the celebrant.

Usage in the Dead or Alive seriesEdit

Birthdays play an important role in Dead or Alive Xtreme Venus Vacation, where they are the subject of week-long gachas where, upon rolling 5,000 paid V-stones once, the player gets a cake to give to the celebrating girl, which supplies the player with an Extra Episode focusing on that particular girl's birthday of a given year (although unlocking the extra episode does not require giving the cake during the birthday period). During the first year of the game (November 2017-October 2018 in the DMM version, and to a lesser extent May 2019-March 2020 in the Steam version), giving a girl a birthday cake only resulted in the girl being given the extra episodes, and rolling the birthday gacha did not supply any additional bonuses beyond the cake, while the gacha generally had past SSR and SRs for various girls (including paid star coin SSRs for add-on girls). It also was initially limited to one 24-hour period on their birthday.

In the second year, however, rolling in the gacha also supplied 10 candles in the girl's likeness, and also had the cake be utilized as furniture inside the Owner Room, with the gacha itself also allowing for a chance to roll for an exclusive Stella swimsuit (based on constellations, and in turn alluding to the Tropical Zodiacs that the girls' birthdays' fall under). Similarly, the extra episodes during the first year did not have any additional elements beyond gifting a cake, but in the second year, the episodes also have the owner supplying the birthday girl with the Stella swimwear as well as photographing them (with the player optionally taking the picture directly). Some of the girls can even get optional SR accessories for their Stella suits during the birthday periods by either paying 500 character coins in their likeness, or in the case of Tamaki and Ayane, paying 10 candles. In addition, after giving the girl her birthday cake during the event period will allow the player to access via the cake icon on the main menu the girls thanking the owner for celebrating their birthdays with them before blowing out their cake's candles and applauding. In addition, the gacha period was increased from a 24-hour period to a full week (or less than that if two differing birthday girls appear less than a week from each other, such as Kanna and Momiji.).

The concept was further expanded in the third year, where the player can not only do all the elements introduced in prior years, but upon gifting the cake can also unlock an exclusive event where the player can win 10 character coins upon winning plus 1000 V-stones via an S-rank on each rank barring S-Rank, which instead has the player unlocking a SSR+ "Promise Ring" as well as a pose of the girl showing off their ring (with the pose being automatically placed in their pose options on the camera menu upon being unlocked), as well as the suit's decobromide for S-rank victories. The Promise Ring unlocks an extra episode where the girls are given their promise rings. However, the player is not required to complete the event to get the pose or ring, as it can be gifted to them especially if the player gives them the cake after the event passed. In some cases, the girls' birthday events during this time has an additonal S-ranked match that allows the opportunity to get special SRs fitting the birthday theme. In addition, accessories could also be unlocked if the player fully awakens the birthday swimwear (this time modeled after birthstones). Gemstones act as the currency during Year 3. In addition, with the exception of add-ons such as Fiona, Nagisa, Kanna, Monica and Sayuri (which instead only feature their paid SSR as well as their birthday suits), the girls' birthday gachas during year 3 also supply some of their SSR suits, including themed suits shared by all the free girls, with the only known exceptions being those released during a collaboration. In addition, presumably to both add in a Capricorn-themed outfit and compensation for her not being released from the paywall before the third set, Monica also got a second birthday SSR, Stellar Capricorn, in addition to Jewel Garnet, with something similar occurring with Sayuri. In addition, add-on girls that were released during the third year also had two birthday cakes issued (one for the Jewel gacha, and the other for the Stellar gacha), while the others only had their cakes issued with the Jewel gacha. While the gacha itself retained its week-long time limit, the birthday event itself, provided the player gave the birthday girl her cake, lasts for two weeks.

Although not explicitly birthdays due to having unknown birth dates, the characters Nyotengu and Kanna have a similar celebration known as Special Days, including being gifted birthday cakes and (in the case of year 2 and 3), swimwear and rings. Nyotengu in her first special day episode implies that "special day" was the term used by Tengu for what humans called birthdays.

The Steam version, while otherwise following the path of the DMM version, released the Stella swimwear early starting with Nyotengu, and also added presents that can be won during the Birthday/Special Day celebration event matches, with each gifted present to any girl rewarding the player with thank you cards, which can be used in a special event shop menu to purchase the girls' favorite food and drinks as well as character coins. Giving 500 gifts to a birthday girl, if the player has said girl, also awards them with a special banner featuring the birthday girl saying "A Special Owner ♪". Although they can be gifted to any girl, more points are given when supplied to the birthday girl if the player has her. Additional prizes for clearing thresholds are also supplied as well.

Below is a table listing all the birthdays in Xtreme Venus Vacation. Note that in certain cases, although they never had a birthday in that year, they will nevertheless have a birthday SSR for that year if released afterward, which will be noted.

** Steam version only

*** Identified as Mystery Venus during the initial part of the event in the Steam version.

Aside from the celebration of girls birthdays, logging in during the player's own inputted birthday will have the girls give their own birthday salutations. In addition, during the first anniversary, Honoka also considered singing happy birthday to the boss when trying to decide with Marie Rose and Nyotengu regarding entertainment to celebrate the occasion, although Marie Rose shot down the idea after reminding Honoka that it wasn't the boss's birthday they were celebrating. Honoka also wished the festival itself a happy birthday in her mission quote for the same event.


  • Nyotengu and Kanna's special day dates, November 19 and September 15, fall around the dates of the release of Dead or Alive Xtreme Venus Vacation and the 2019 Tokyo Game Show, respectively.
