Alan is a young man with short brown hair and a slight frown. Similar to all Grim Reapers, he wears glasses, a black suit (though he wears a bolo tie), and has yellow-green eyes.
Alan is a member of the Grim Reaper Dispatch Department and works directly with Eric Slingby, William T. Spears, Ronald Knox, and Grell Sutcliff. Alan seems calm most of the time, but can become angry and shout. Like the other Grim Reapers, Alan has little tolerance for those who break the rules or slack off

Alan has a disease called "Shi No Toge" (死の棘) literally meaning "The Sting of Death" or the "Thorns of Death". The Thorns are contracted when a soul destined to die becomes vengeful, fighting against the Grim Reapers that would reap it, attacking and manifesting itself in the form of the thorns, which eventually suffocate the heart. There is no known cure, however it is rumored that it can be cured by the sacrifice of one thousand pure souls. Alan is the only known Grim Reaper to ever contract it.
