History in Edelweiss starts off pretty fun. Five young guys, under the supervision of their teacher, are sailing on a boat. Their goal is to reach a remote island. It is at the local school that the guys will finish their education. Everyone is happy – after all, all the students at the school are exclusively young girls. The young men want romance and relationships. As soon as they land on the shore, they immediately run to look for an educational institution. One old man showed them the way to the beach. Thinking that there are young ladies there, the characters head there. Unexpectedly, they are met there by a living prohibitory sign. It drives them out of the territory with blows. Everyone runs one by one. The player controls the main character, named Kazushi. On the way, he falls off a cliff, meets two girls who take him to school.

Gaining knowledge in Edelweiss is not such an easy task. Not only are newcomers considered perverted, but they are also housed in a dirty barracks. Everyone thinks that they need to run away from here. They are already approaching their transport, as an earthquake begins. The island rises from the water, and it is not possible to leave. They have to continue their studies. And the institution is a strange place. First of all, they teach witchcraft and alchemy. Among the surrounding people are many extraordinary personalities. For example, the teacher Miss May, who does not remember anything from her past life. Or the student Natsune, who begs you to find her. At the same time, the player's task is to find the character his beloved. There are several candidates, but in the end you can be left without a partner. You should be careful about the actions and dialogues. There are erotic scenes, so only an adult audience is allowed to play.
