About this game

Vitamin Z is the sequel to Vitamin X , taking place after the events of the previous game.

Former protagonist Yuri Minami leaves the school to study abroad, and her position of teaching the infamous Class X (now known as Class Z) is taken by new teacher Manami Kitamori.

Manami, having just graduated college, is eager for the job until she learns of the A4 (Aho 4): the four most troublesome students of Class Z who refuse to take school seriously.

The A4 is made up of the wealthy Tenjuro Narumiya, who loves to surf and is intent on finding his future wife, but despises studying; Chisato Fuwa, the best friend of Tenjuro who is focused on protecting him due to a bond between their families, but has trouble arriving to school on time for extra lessons; Yakumo Tachibana, a short boy who lives a double life as an idol in a boy band, and refuses to put in the effort required for good grades; and the perverted Arata Mine, a gifted tennis player who would rather put his time into building a harem of girls than studying.

As in the predecessor, Manami must choose a student to tutor and then collect a combination of Love points (by letting their mistakes pass) and Study points (by correcting their mistakes) in order to obtain the best of a possible three endings.

The B6 (Baka 6) make a return as teachers, with one assigned to each student in order to aid Manami in handling them.

Alternatively, Manami can choose one of the P2 (2 Princes) of the student council to help her deal with the A4.

Kei Hōjō and Nachi Hōjō are twin brothers who are devoted to their jobs and each other.

Like the A4, they also have three endings each.

About PlayStation 2

The PlayStation 2 (2000) is the best-selling game console in history, with a library exceeding 9,000 titles that spans everything from budget shovelware to genre-defining classics. That massive volume means PS2 collecting is accessible and affordable overall, but a handful of low-print-run RPGs and cult titles have become genuinely expensive — a common pattern once a console's original audience grows up with disposable income.

Gamevaro tracks Vitamin Z for PlayStation 2 with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.

Adding Vitamin Z to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This PS2 release dates back to 2009.

Rarity & condition

Only a handful of market sales have been tracked for Vitamin Z, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common PlayStation 2 titles.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
