In the Bleach Bootleg, a section was included with questions and answers from the captains and vice-captains of each squad as part of the Gotei 13 Recruitment Fair. The following was the 5th Division entry for the Recruitment Fair.
1. What kind of individuals are you seeking?
2. How would you describe the atmosphere around your division?
The captain is gone and there are still a lot of days when I have to stay in bed, but essentially it's a very peaceful division with a wonderful atmosphere.
3. What do you require of new recruits?
People who wouldn't betray anyone...
4. Some words for the shinigami recruits.
Let's protect the 5th division together!
Frank talk!! with the 8th Division lieutenant, Nanao Ise
H... Hinamori-san, is your health better now? If you have any troubles or concerns or that sort of thing, you can talk to me any time, just ask for me! Let's read together again sometime.
It is notable that three of the current lieutenants were once associated with Squad 5, personally recruited by former Captain Aizen after their graduation from the academy. However, two of the three (Renji and Izuru) both found themselves leaving for other divisions before moving to their eventual lieutenant position. Only Momo Hinamori remained and rose to her position in the same division as her initial recruitment.
