Anime & Manga

Hyperdimension Neptunia: Megami Tsuushin

5pb. is a minor character who appears in Chapter 15. She was enlisted by Histoire to help the goddesses' idol group. Histoire tries to get 5pb. to show herself to the goddesses but as she is shy, after seeing her for a short time, she fled but promises that she will help them. 5pb. writes their songs and trains the Noire, Blanc and Vert in how to be an idol. Due to Neptune naming the group MGM-48 before anything was official, the idol group balloons up to 48 members.

On the day of the concert, Neptune being unable to sing and unaware of the fact nearly ruined the concert immediately. However, Nepgear, IF and Compa are able to stop Neptune. IF hands the mike over 5pb. and she was able to salvage the concert. Seeing how good 5pb. is, Neptune makes 5pb. her teacher in how to sing. Noire pities 5pb.

  • In the original Japanese version of the Hyperdimension Neptunia, IF refers to her as "5pb.-chan". As there is no direct way to translate the suffix "-chan", the English translation chose to give her a "real name", Lyrica, for IF to call her instead.
