Just when I thought the only item that we need to spend on for 「Kiseki: Sobito Of That Day」 is the pamphlet, we finally received news for another 3 items. They can be bought at [TOEI e-shop], and somehow the links aren’t ready. They can also be bought at the cinemas screening the movie.
[edit2] Other than the pamphlet, the rest of the items are currently sold out. NOOOOOO!!!
 Updated with actual photos of the goods.
