Welcome to STU48: My Idol, My Battle — the official mobile gaming experience that brings the heart and soul of Japan’s only wide-region idol unit to life! Rooted in the breathtaking Setouchi region, spanning seven prefectures and connected by sea, STU48 isn’t just an idol group — it’s a movement, a dream, and now, a full-throttle 7-player competitive battle game.

🎮 Step Into the Storm of Passion and Rivalry!

• 🔥 Rise Through the Support Density Battle
  Join forces with your favorite STU48 member and fuel their journey to stardom! In intense 7-player head-to-head matches, every vote, every move, and every victory builds their Support Density — a unique metric that reflects how deeply fans believe in them. As their support grows, so does their story.

• 💬 Unlock Hidden Sides of the Idols
  Through exclusive story events, card awakenings, and personal messages, you’ll discover intimate secrets, behind-the-scenes moments, and emotional bonds only true fans get to see. Feel the warmth of a handshake, the thrill of a shared dream — and maybe even catch a glimpse of a secret crush.

• ⚡ Challenge the Idols in Real-Time Online Battles!
  Ditch the solo grind. Step into the live 7-player online arena, where real fans from across the Setouchi region battle it out — and yes, you might just face off against the real STU48 members themselves during special live events!

  🌊 Special Event: "The Setouchi Dash"
  Experience unique racing scenarios where idols race through historic towns, across floating bridges, and through cherry blossom storms — all while you control their every move. Win, and you might earn a rare member-signed item card or even a virtual handshake!

• 🎯 Designed for One-Handed Mastery
  With simple vertical swipe controls, auto-assist timing, and real-time match tracking, you can play anytime — on the train, in a coastal cafe, or under the glow of a summer sunset. The game is built for fans who want to feel the rhythm of battle, not fumble with buttons.
