Because this is a search-driven article, we must address the elephant in the room: Is it legal to download this?

Not legal, but practical. Your risk is not lawsuits; it is malware . Only 20% of the search results for this game lead to safe files. If you download from a random blogspot blog, you risk adware or spyware.

Bandai Namco (the license holder for Naruto games) has the right to issue a DMCA takedown to the developer at any time. This is why the game is not on app stores. If that happens, the download links vanish.
