viviON, the parent company to Japanese content platform DLsite, announced on May 8 that it would be launching a brand-new indie publishing label, aptly named viviON Lab. Furthermore, it was revealed that Moon Princess and 7 Days To Think About It would be the first two titles published under the label.
According to viviON, throughout the fiscal year 2026, the company will be focusing on strengthening their game related business, with plans to launch multiple different game-related projects and initiatives. Marking the company’s entry into the indie publishing business, viviON Lab is first such project.

Moon Princes is a Wuxia-themed “daughter-raising sim meets martial arts” RPG created by Chinese developer Egg Hatcher. Much like the developers’ acclaimed title Volcano Princess, Moon Princess will put you to the difficult task of raising your daughter. Through training, combat, exploration and management, the heroine’s life and destiny can branch into over 50 possible career endings and more than 20 different relationship outcomes.

7 Days To Think About It is a psychological horror created by Italy-based solo developer silver978 and Mankind Games. What starts as the protagonist’s feelings of “being stuck in life” leads them to actually get stuck at home. Overthinking whether to accept the invitation to go out with your friends, you spend 7 days trying to make the decision. However, each day, the furniture in your house randomly changes places, and you’ll be tasked with “remembering” how its actually arranged.
Aside from these two games, the label is already making discussions and preparations for adding new titles to their roster. According to the company, viviON Lab is not bound to a specific theme or concept, as its aim is to help deliver a wide variety of diverse indie games to the world. This means they will be picking up new titles regardless of team size, country of origin or genre. Considering that their first two titles come from a Chinese and Italian developer respectively, it seems like viviON Lab will be involved in a much wider range of works than those previously published by DLSite.
Moon Princess is set to release in 2026 for PC (Steam). 7 Days To Think About It is coming soon for PC (Steam), with a playable demo currently available.
