Project Sekai is a rhythm-based mobile game that brings together original characters and vocaloid performers in a shared musical space. The player takes part in live performances by tapping notes in time with music tracks from a wide range of genres. Each performance is paired with animated sequences featuring both human and vocaloid members, depending on the selected team. The game does not focus on competition alone but connects songs with character-driven narratives that are specific to each unit. These stories are unlocked as progress is made and often reflect the emotional themes of the songs they perform.
Rhythm System and Performance Flow
The main gameplay revolves around timing inputs to a track’s rhythm, using taps, holds, and slides across a note path. The challenge increases with speed, note density, and song complexity. Visual presentation varies depending on the characters chosen and the background stage settings. Project Sekai also allows customization of gameplay visuals to reduce distractions or enhance personal preference. Scoring is based on accuracy and combo streaks, and each completed track rewards experience points, in-game currency, and items used to improve your team. New songs are added regularly, each offering a different experience in terms of pacing and visual design.
Units, Music Themes, and Characters
The game’s structure is organized around several character groups, or units, each of which represents a specific style and concept. These include:
· A school band focused on rebuilding old friendships
· A rising idol team learning how to work together
· A street performance group exploring ambition and rivalry
· A fantasy-themed troupe using theater to reach audiences
· A private online group dealing with emotional isolation
Each unit features both original human members and vocaloids, with some songs performed together, while others are unit-exclusive. Players can freely assemble different teams to explore alternative arrangements and combinations during live shows.
Story Progression and Event Play
Story content in Project Sekai is presented through a combination of text dialogues, short animated scenes, and voice acting. Players unlock new chapters by increasing character bonds and progressing through event-based missions. Events occur regularly and introduce temporary story arcs that often connect to limited songs or costumes. Participation in these events earns ranking points and exclusive items, encouraging repeated play during active periods. The game also allows for casual multiplayer sessions, where up to five players can join the same performance and complete it together for shared rewards.
