Taihen, The Blue Outlander

Activating a device that traverses across space-time, Taihen, a mysterious outlander with deep blue skin, appears to have landed in a cave. Unbeknownst to him, this apparent blunder may cost him a ton due to a series of unfortunate occurrences. Caught in the middle of many dilemmas, he finds every opportunity to leave. Or, he may change his mind viewing humanity as something worth staying for.
