So I'm not the biggest Tamagachi fan, last time I had one like this must have been over 15 years ago in elementary school. But I'm an avid Evangelion fan so I MUST have this before they end up being discontinued. I have three colors: Kaworu, Asuka and Pre-Rei. Out of the three, I've only opened Tentative Rei to see how one of them works. The screen is small and shows very nice pixel art, and the buttons are very small and difficult to press. Interacting with your pet angel is very simple. Despite being a Japanese language product, the mechanics are easy to understand without a guide. If there is any confusion, there are a few helpful blogs that cover these topics. Overall, even if you don't intend to own a pet, the item is very high quality and the design is very attractive and every color scheme reflects Evangelion. Characters. There are no serious claims here.
