My Dear Miss Medical Examiner - Chapter 102.2

Strength.... That's all that matters in the end.

After being abandoned by his own family, and shunned for having no mana in a world dominated by magic, ex-prince Arvell Relas Vispia was forced to live on the streets with whatever meagre money he had left.

However, fate had something else in store for Arvell.

After meeting the spirit inhabiting his amulet, Arvell gets reborn as a Nephilim.

A being that has the powers of a god.

Time, Space, Life, Death.

All submitted to the authority of a Nephilim.

Betrayed by those he once called family, Arvell swore to get revenge.

Revenge on all those that mocked him and shunned him as a 'failure.'

Revenge on those who betrayed him without a second thought.

This is a tale of how a young prince shunned by the world as a 'failure' rises and ascends to the pinnacle of strength.
