Once you have a legitimate ISO, follow this guide.

Unlike the 3DS Inazuma Eleven GO games, Strikers 2013 has no full English translation patch. The menus are in Japanese. Luckily, the game is very visual. You can navigate using guides:

First and foremost: There is no official Android version of Inazuma Eleven GO Strikers 2013. Level-5 never ported the Strikers series to mobile devices. Any website claiming to offer a direct ".apk" file of this specific game is either distributing a fake application, malware, or a poorly modified fan project.

The correct technical term you are looking for is not an "Android ISO" (as ISO is a disc image format for CD/DVD/ Wii games). You are looking for a Wii ISO (or WBFS file) of the game, plus a Wii emulator for Android to run it.

Unlike the DS/3DS games where you control players on a top-down grid, Strikers 2013 is played like a standard football game (similar to FIFA or PES) but with a heavy anime twist.
