Seems like this isn't the first game about those characters called Mina and Mana yet scarcely this mastery can help you in the event that you do not understand japanese - all of the texts are inside this language so may be you shouldn't to fret about any narrative plot or dialogs in any way. On the opposite side should you love the experiences of nice appearing anime girls with large eyes and might not be so large yet definitely already sticking out tits then you probably have to give this game a chance - only observe the scenes and then click the next button if it will become accessible to advance further. Thanks to particular yet still colorific artstyle you may even attempt and thnk your personal story about two horny schoolgirls sneak glancing at a dude they like in the swimming pool...
