Ryūji Saeki

Ryūji Saeki is an A-rank All-Rounder and a member of Kusakabe Squad.

Appearance
 Front= Back= Saeki has black hair parted in the middle (with the rest swept briskly over to the left), standing at a height just under Satomi. His high-collared uniform is black except for an olivedrab color on the biceps and chest pockets; it has white stripes running down the sides, as well as a white stripe lining the zipper. The Kusakabe squad logo is located above his left chest pocket.

Personality
He is not hesitant to speak his mind, or even question his captain — the former of which rings especially true when it comes to the cooking ability of other agents, much to his enthusiasm. When not engrossed in home economics, he wears a serious but relaxed disposition.

Border Enlistment Arc
Saeki is mentioned as one of the eleven Fūjin candidates by Jin for his Black Trigger.

B-Rank Wars Arc
For much of the most recent season, his squad (along with Katagiri Squad) went scouting for potential recruits outside of the prefecture.

However prior to the Final Round, they came out and was briefly shown with Uno as he called out to Satomi.

A-Rank Squad Evaluation
He comments that Yuba's presence would ensure that the squad will "run a tight ship" for the first phase, not long after he asks Kusakabe if Kuruma's relative slowness be fine if the squad is careful for the second phase.

Phase 1
He was shown happily reacting to Ikoma and Kon's dinners and wishes he could eat the food while also commenting how cool they are.
