Each members came out one by one, they were given some 'personal time' to interact with their fans like what shown above. The message written on the banner is "Congratulations for the graduation Shinoda Mariko"
The next is Akimoto Sayaka. Cladded in yukata, she walked to the crowds with a megaphone in order to speak something to her fans. The message on the banner is "Congrats for the graduation, Akimoto Sayaka-san! Meeting with you is a miracle!"
The last for this 'session' is Itano Tomomi. The message on the banner is "From now on too lets walk with Tomo together as 'Tomo' (friends)"
After this, fans who were there for the farewell session with Mariko, Tomochin and Sayaka walked out of the venue, the sessions for Nakatsuka Tomomi, Matsubara Natsumi and Komori Mika were done later that night.
After that, It was a turn for Matsubara Natsumi fans. It was done about 2 hours after Tomochin's session. The message written there was "Congrats for the graduation Natsumii, starting from this path you'll be an actress".
The next is Nakatsuka Tomomi, unlike the session before, she was able to pas the fence and greet her fans closer. The message on the banner is "We're always be Nakatsuka Tomomi oshi! We're glad we're able to meet Tomo-chan "
The difference between the first three member and the last three was that the last three have no more activities anymore, meaning they will be fully graduated. The pics above are when they took down their photos on AKB48. Sotsugyou omedetou, Matsubara Natsumi, Nakatsuka Tomomi, and Komori Mika!
