Personality:
From Tasuki no Miko's home office in Cucamunga, here's Watase Yuu's take on Chichiri:
"An elusive, mysterious person who wears a mask and is always wandering. Can be silly or serious. A neutral character who doesn't break the Suzaku Seishi stereotype. On the surface, Tamahome and Hotohori may seem the leaders but he is the leader behind the scenes who looks after them and counsels them. (He is the adult who looks after the boys) He uses various spells taught to him by Taiitsukun. Having no selfish desires, he keeps rather distant from ordinary men which probably makes him hermit-like."

My own thoughts:
Personally, I didn't get much from the series about Chichiri's personality (most of what I know I learned from other character descriptions! See bottom of page)... The poor guy is scarred emotionally for life, but he's very strong to have been able to pull through it and still be there for Miaka and the rest. I mean, how many of us have the resilience to be able to say, "yes, I've had a hellish experience, and I carry around the weight of my guilt every day, but sure I'll listen to your problems and give you advice."?

Rock of Gibraltor?
I've seen Chichiri described as having the most together and calm personality, doesn't flip out, etc...I don't see it. I think he's in SD form often enough that his reactions to various events are not all that calm but often rather humorous. Just how "together" is he, really?

However (and here's where I reverse my position entirely ^_^)... Chichiri can be very sensible, practical, and logical, and is a very good source for advice. He definitely shows the wisdom of those extra few years he has over the other seishi, coupled with his experiences. I guess I do see it after all... *sighs* He's just so awesome!

At any rate, Chichiri's the only magician on the Suzaku side, and God knows the shichiseishi need a magician to even stand a chance against Nakago :(.
The gang definitely needs his wise and strong shoulder to lean on (or cry on) in times of trouble, and his cool-headed thinking has gotten them through a crisis more than once.
