“This is the notebook that caused Gelus to die when he saved Misa. It would pass from Rem to Misa and eventually Mikami. This is the notebook that played the key role in the battle with Near.”
Gelus's notebook is black with "arvc-5" written in white on the front. The inside of the notebook contains white, ruled pages.
Gelus, a Shinigami, fell in love with Misa Amane and used his Death Note to kill the man who was destined to kill her. Gelus died as a result, leaving only his Death Note behind. The notebook was found by Rem, who took it to the Human World and gave it to Misa, who Rem believed was supposed to have it. Light Yagami eventually has Misa give up ownership of her notebook and sends it to Teru Mikami. The notebook is discovered and confiscated by Gevanni, and is eventually burned by Near, after which it disappears from the Human World.
- The writing on the front, ARVC-5, is in reference to the inherited gene Arrhythmogenic Right Ventricular Cardiomyopathy 5, which can cause sudden heart attacks in people with the gene.
