Tsubu: Blood Type Personality

Discover your true self through blood type — kawaii style. ✨

Tsubu is a soft, kawaii blood type personality app inspired by Japan's beloved ketsueki-gata (血液型) tradition. Read your blood type personality, check compatibility with friends and crushes, and get a daily fortune just for you — all wrapped in a gentle, glassmorphism-pastel design.

★ WHAT TSUBU GIVES YOU

• Four languages — English, 日本語, 한국어, ไทย. Choose during onboarding.

★ KAWAII TO THE LAST PIXEL

Eight unique chibi mascots (one for each blood type, in two genders) painted in soft pastel watercolor. Floating bobbing animations. Sticker-style outlines. Glass cards. Every screen is a quiet little world.

★ JAPANESE BLOOD TYPE TRADITION

Tsubu's personality and compatibility readings draw on the Japanese ketsueki-gata tradition popularized by Nomi Masahiko (1971) and rooted in Furukawa Takeji's 1927 work. The Nomi school is the standard reference for blood type personality and compatibility in Japan and Korea — and Tsubu honors that lineage.

★ JUST FOR FUN

Blood type personality theory is a cultural belief, not peer-reviewed science. Read it the way you read horoscopes — a fun mirror, not a verdict. Be kind to people whose type "shouldn't" match yours. 💖
