You know them. But do you really? Sekai helps you discover new things about all your favorite people. Ask something you want to know, pick who to hear from, and see what everyone says. Then choose someone and see your answers come to life in a short, sometimes ridiculous story starring the two of you. Chat about what happened, collect custom stickers of you and your friends, and unlock new experiences every day with a daily prompt that everyone answers. Be silly, be honest, or ask the weird question. On Sekai, there's always more to find out.
