Type Moon: I, Mordred, Are So Filial

Regenerate into Mordred and activate the filial piety system.
In theory, as long as you listen to your parents, you can get super high rewards.
But the problem is...
"I understand the truth, but what does this Frostmourne mean?"
All in all, this is probably the story of a transmigrator who was reborn as Mordred and fought hard not to be stabbed to death by Artoria.
