When one sets their eyes on their Oshi they must do so with the intent to see them struck down. Take everything from your Oshi and give nothing in return. Demand more, flay yourself until they are of your mind, concern yourself not with their rise and drink deep of every failure they make on their path. Truly loving your Oshi should see them being torn apart by thousands of screaming lunatic followers at the height of their career.
To even accept a Kamioshi is to fully embrace the dissolution of their purpose and the eternal aeonic slumber of oblivion when they have reached their highest peak.
