Before watching the recent anime arc focusing on Itachi, I had assumed that he
and Shisui were roughly the same age. But in episode 452, Shisui appears as a
full-fledged ninja alongside the 6 or 7-year-old Itachi when the latter was
still a first-year student.

Also reading into things further, Shisui awakened his Mangekyo after
witnessing an unnamed friend's death in the Third Great Ninja War, so he must
have been old enough to participate there.

Is there any further information that can help nail Shisui's age down?

How old is Shisui compared to Itachi?


At the time Shisui died, he was 16 and Itachi was 12-13 years old. He met
5-year-old Itachi a year after the Third Great Ninja War. Assuming Shisui was
3 years older than Itachi, he should have been 7 during the war.

Chunin rank and above are allowed to participate in the wars. Considering
Shisui was extremely talented, it makes sense that he was a Chunin at the age
of 7.

Itachi was 12-13 and Shisui was 16.

Because Shisui died before Itachi left the village and Itachi left the village
when he was 13, this means that Itachi couldn't have been 15.

This also means that if Itachi would have been 15 that the coup d'etat
would've happened. Which it didn't.

I would like to point out; we have no idea how old Shisui was when he
graduated from the Academy. At the time, the average age was nine (see Obito
Uchiha and Rin Nohara). We don't know whether or not Shisui graduated early.
That plays a key deciding factor here, considering he met Itachi approximately
two or three years after he graduated.

If he graduated at the average wartime age, this would make him somewhere
around eighteen to twenty years old at the time of his death. Thus, making him
six years older than Itachi, give or take. Perhaps he graduated at six, like
Kakashi, or maybe seven. Possibly eight. We have no idea. We don't know how
long Shisui fought in the war for either. What if it was a year? Or more?

However, gauging his visual age 18-20 makes the most sense. In addition, have
you seen the difference in height between Shisui and Itachi when they first
met? There's too big a difference for there to simply be a three-year age gap,
in my opinion.

Also, you need to factor in Shisui's height and weight stats from the
databook. At the time of his death, he had the height and weight of an average
adult male. He couldn't have been less than eighteen. I like to believe he was
nineteen; six years older than Itachi.
