Parafen...Paraphan... Stuff.
Ahh, Sana's Rap Machine.
You will end up seeing this
device in EVERY KoDoCha episode.
You know it is coming when Sana
yells into it and then shows
the machine playing back her voice, in one of the
infinite number of playback distortions.
It can also be plugged in to Sana's Babbit-synth
(A keyboard shaped like a babbit head)
when Sana needs to play along while rapping.
Sana is always in constant with her manager Rei with the help of her beeper.
Whenever Sana needs to get Rei's attention (or vice-versa) she just pushes the
appropriate button to get the other's attention.
However, these beepers don't make noise, they are vibration beepers, and NOT
mild vibrations either. These vibrations can move cars. Sana and Rei use this
form of communication frequently.
In episode 11, Sana gives Hayama one of the remaining 3 beepers.
From episode 14 on, I think Hayama regrets accepting it. :)
Hayama's Camera
This camera is the primary cause of the classroom war
that transpired in episodes 2,3 and 4 due to the snapshots of
the Sensei Michiya and Tanaka in rather comprimising positions
in the teacher's lounge.
It was also this camera that was responsible for ending the classroom
war when Sana used this camera to get some bargaining material to
get the photos back. Namely, Hayama with his pants pulled down.
