About This Game

One Year of Special Lessons with My Little Sister Luri is a story-driven raising simulation and visual novel about spending 40 weeks together with Luri, your little sister, while her parents are away overseas.

After meeting again for the first time in five years, Luri begins living with you. How she spends this year—and what kind of person she grows into—will depend on the choices you make together.

Plan each day and help Luri grow.

Choose how to spend your mornings and evenings. Teach her at home, visit the city for more effective lessons, work to earn money, go shopping, or simply spend time together.

Develop five different life skills: Cooking, Academics, Athletics, Craftsmanship, and Confidence. As Luri improves, new conversations, activities, events, and opportunities will become available.

Take on skill exams.

Luri can challenge a series of Beginner, Intermediate, Advanced, and Master exams. Earn medals in each field and help her discover what she is truly good at.

Share a year full of memories.

Visit an amusement park, attend a summer festival, go camping, spend time at the beach, experience school life, and enjoy many smaller moments together at home and around town.

Some of the most important moments happen during quiet conversations. Listen to Luri's worries, respond to her choices, and build memories that may influence her future.

Her future is shaped by the year you spend together.

Luri may discover a dream of becoming a chef, teacher, athlete, designer, or idol. Your decisions, her growth, your relationship, and the memories you create together can lead to a variety of different endings.

There is no single correct way to spend these 40 weeks.

Study hard, enjoy everyday life, pursue a dream, or simply try to make this year something Luri will never forget.
