Pre-orders for any version of the game include the downloadable "School Shirt Set" content, which includes the "Swimsuit Normal", "Swim School Swimsuit" and "Old School Swimwear" costumes.
PlayStation 4 users who already own the original LoveR will also be able to switch to LoveR Kiss by purchasing the "Kiss Upgrade" add-on at 5,436 yen, which should be released about a month after the release of LoveR Kiss.
