Bishoujo Brand 'kawaiinium' Launches Steam Store Page for Ren'ai 0 Kilometer

kawaiinium is pleased to announce that the Steam store page for its third title, Ren'ai 0 Kilometer (originally developed by ASa Project), is now live. Fans can now add the game to their Steam wishlists in anticipation of its global release.

Originally released for PC in October 2011 as the fourth title from ASa Project, Ren'ai 0 Kilometer went on to receive ports for the PlayStation Portable in January 2013 and later for the PlayStation Vita, earning wide popularity as a romantic adventure game.

Centered around themes of family and everyday romance, Ren'ai 0 Kilometer blends heartfelt storytelling with over-the-top humor and snappy, lighthearted energy. The Steam version faithfully preserves the quirky charm and expressive characters that made it a standout hit, even for newcomers to the visual novel genre.

As with all kawaiinium titles, the Steam version will feature HD optimization and multilingual support (Japanese / English / Traditional Chinese / Simplified Chinese).

Summary:
The Yazaki family (four brothers raised by their father) and the Kinomoto family (five sisters raised by their mother) live next door to each other. Each family secretly wishes for the child they never had—one wants a girl, the other a boy. One day, the parents make a radical proposal: “Let's swap one child for three months and see what happens!”

And so, the second son of the Yazakis, Kyouichi, moves into the Kinomoto household, while the second daughter of the Kinomotos, Sakuya, goes to stay in the Yazaki house.

The Kinomoto girls, unsure how to treat Kyouichi at first, gradually accept him into their lively home. It's a bit awkward to just start calling him “Onii-chan”, after all.

Kyouichi, overwhelmed by the all-female environment, is simultaneously drawn to the unique warmth and the different dynamics of their familial chaos. But the 3-month deadline looms ever closer. Through their time together, Kyouichi, Sakuya, and both families begin to discover what family truly means. Will they return to life as it was—or choose a new future?

■ Planned Release Date
