Bab 35: Chapter 35: The Evil Dragon Wants to Go to the Human World?

Lance, the Undead Mage, teaches you online how to properly use a nemesis.

For Lance's nemesis... it's somewhat tragic, failing to kill Lance while alive, and after death, facing the risk of being summoned from Hell by Lance to be used up as a "battle companion".

It's somewhat unwise to be the enemy of an apprentice Grim Reaper who has signed a contract with Hell.

Death God Solomon mourns for Lance's nemesis for a second.

Lance is his partner, he and Lance are in cahoots; he ought to protect Lance and that means protecting Lance.

Having collaborated for nearly a thousand years, why would he protect Lance's nemesis instead of Lance?

If Lance's nemesis could kill Lance... then he would be quite willing to support Lance's nemesis.
