According to the photobook description and google translator, the photobook will have some shots of Airi in school and after school activities. The title also has “spring” in it so we can assume that the shots will have something spring related, such as spring sports.
Other than that nothing else has been released, but being a very loyal H!P fan I’m sure whatever is released will be an amazing one.
Hopefully everyone can support Airi and reserve a copy of her photobook.
The photobook will be released on 5/23. (She is also releasing another photobook on 6/23, but no other information has been released yet.)
