Castlevania: Grimoire of Souls

Siliconera's translation of the story:
"In a future where Count Dracula has been completely vanquished, people thought they had finally achieved eternal peace.

However, a letter sent to Genya Arikado spelt the end of that peaceful age.

“The Grimoire has gone berserk. Count Dracula has been revived.”

In order to confirm the message in the letter, Genya Arikado heads to the sender’s location…"
