Aim through a battlefield of falling cherry blossoms. Ei-Oh-Den is a vertical scrolling shooter RPG set in a Japanese historical fantasy world, with story-driven battles and character growth. AIM TO ATTACK. TAP TO DEFEND. Instead of moving your character, choose the direction of your shots. Tap with the right timing to guard against enemy attacks. Read the battle, line up your aim, and strike. LEARN WITH RETSUMA Your first New Game begins with Retsuma’s practical tutorial. Watch a training dummy being defeated, tap dropped EXP and GOLD, learn how to retreat through the menu, and check your character’s growth. Gameplay footage, speech bubbles, and pointers explain each step. Replay the tutorial from Options whenever you need a refresher. COLLECT, RETURN, AND GROW Tap the EXP and GOLD dropped by enemies to collect them. Collected rewards are added when you return to the menu after an interruption, retreat, game over, or stage clear. Build up Michitaka through repeated expeditions and returns. CHERRY BLOSSOMS AND MUSIC Enjoy a Japanese disco atmosphere in the music player: the background girl dances as her hair and sleeves sway amid cherry blossoms and light. Refreshed sign lettering and an opening transition from Michitaka’s arrival through falling blossoms to the title bring the world to life. FOLLOW THE STORY Is a gifted talent a blessing or a curse? Discover the story of Ei-Oh-Den as you fight and grow stronger. Playable in Japanese and English. Visit the official website for Retsuma’s tutorial videos and an early-game guide.
