About

Ninja Sekai

Features
Read full description

Ninja Sekai is a game about ninjas fighting with ninjutsu. The game features a variety of cool ninjutsu that can inflict different damage on enemies based on the player's hand seal speed. The most critical aspect is that ninjutsu is divided into five attributes: Metal, Wood, Water, Fire, and Earth. These attributes have interactions, so players can use corresponding ninjutsu to counter enemies based on their chakra attributes. Additionally, ninjutsu can be categorized into different types such as offensive, defensive, and supportive. Players can upgrade their favorite ninjutsu through battle rewards, which will enhance all its attributes. The game also features various protagonists that players can recruit. Some protagonists possess strong talents, allowing players to cultivate different characters to face various enemies. As players fight against enemies of different levels, they can gradually grow from a Genin to a Chunin, eventually becoming a renowned Jonin. There are no in-app purchases or ads in the game. All resources are obtained through battles with enemies. The game will continuously update, offering richer ninjutsu, characters, and enemies, making battles increasingly fun.
