Project Seinarukana -The Spirit of Eternity Sword 2- combines features of visual novels and role-playing games. The action takes place in a universe where the great Tree of Time exists. Each of its branches is a world where events went a little differently than in neighboring realities. And in one of these branches lives an ordinary-looking boy, in whose body the soul of an ancient evil deity is imprisoned. The child tries his best to control his emotions, not allowing the monster to escape, but in vain. Other possessed people unleashed a destructive war, in which the baby was thrown into another universe. Now his goal is to return home, save his world and friends.

The developers have implemented the following elements:

• Seinarukana -The Spirit of Eternity Sword 2- combines RPG and novel mechanics. In dialogue with other characters, the gamer can choose various options for answers and actions. Battles take place in squads of 3 heroes, corresponding to different tactical roles.
• The protagonist can become stronger by enhancing his abilities and acquiring new skills. Artifacts play a special role in this. By creating a powerful weapon, the gamer will make the upcoming battles much easier.
• Opponents are represented by different classes, with their own characteristics and disadvantages. This encourages the player to carefully consider their equipment and battle tactics, as the outcome of the game depends on this.
