While most of Japan has been relatively peaceful, the south of Japan has been less fortunate in those terms, having to fend off Sauron's troops from getting any further up the country.
Izuku has been learning about how to be a Ranger when the Gate was attacked and became the only survivor, though that was due to becoming banished from death by being linked with Celebrimbor.
With Japan having embroiled in war between good and evil, people from different backgrounds/races versus Sauron's army, will Izuku successfully work with Celebrimbor in taking down Sauron's forces?
How will everyone feel about having a seemingly immortal person roaming trying to take-down the forces?
