Natsumegu

Natsumegu is a Japanese adult romance visual novel set in the heat of summertime. The player is Atsushi Watabe, a high school student who gathers his friends to celebrate the summer break upon learning that his childhood friend, Yukako Shinonome, will be moving away soon. Throughout the summer break, Atsushi spends plenty of time with Yukako, as well as the half-Japanese tsundere Celes Alford, the boisterous Miri Inui, the big-sisterly Madoka Kobayakawa, and the petite but clumsy Hotori Nojima.

One of the game's distinctive features is the RES (Random Event System), which displays a random selection of possible choices the player can make instead of each playthrough containing the same choices. Depending on which choices the player selects, the game will branch out into different routes to conquer each heroine. The game is set up so that it is easiest to enter Yukako's route on the first playthrough, since her affection level is higher than the other characters (though it is possible to conquer other heroines by choosing options that increase their affection levels).

The Windows version includes sexual content that was omitted from the mobile and console versions.
