I felt like posting a short review as everyone I've talked to about this game is unsure about this game. I may do more of these in the future, but as of now I'm not sure.

Mind zero is a JRPG from Zero Div, Aksys Games, and Acquire.
Most have said it resembles the Persona games, and I have to say I agree to a certain degree.

I this game, you play as Kei, a stereotypical anime protagonist, in the fact that he is brooding and seems to just be bored of everything. Kei along with a "Colorful" cast of character gain the power of M.I.N.D.(Major inner node displacement) which allows them summon an mirror version of themselves from a different realm... And here's where the resemblance to Person starts.

And how do they get this power you ask? Well, they appear in a shop where a blue haired, big breast, blindfolded woman called the undertaker tells you to choose a weapon out of the thousands of weapons in the shop. Choose the wrong one, and the Mind consumes you. Choose the right one, and you and your mind enter a contract.

In this game you explore dungeons in order to complete quest, advance the plot, or just to level grind...Which even in beginners mode is something you MUST do.

Besides exploring dungeons, you can "visit" characters, as in you click on a person icon on the map and that's talking to a character, by doing this you get quest or learn stuff about that character.

And speaking of the characters, you're privileged by having such party members as:

Sana Chikage: A tomboy who loves exercise...Yes that's pretty much it for her. but I notice she resembles Chie from Persona 4.
Leo Asahina: An energetic boy(With a ridiculous hairstyle) who has a compulsive need to online shop. He's kind of a mix between Yosuke and Teddy from Persona 4.
Yoichi Ogata: An old detective. He has a hint of Naoto from Persona 4.
Kotone Shiragiku: A Japanese girl who's vary traditional and shy. Yukiko from Persona 4.
Lina Albertine: The youngest of the group and is a privileged girl and the groups MIND expert. I'm not sure if there's a character like this in the other persona's, but none the less, probably the most interesting character.

As of now I have not beat the game. But that's not from a lack of trying, it's from being tired of having to sit there to grind. But I have done enough that I feel I know what should happen. All around, the combat in this game is well done, character poorly written, and the story is simple.

I give Mind Zero for the PSVITA a 4/10.
