Manaka Mukaido

One of the students from Shioshishio. She is an indecisive middle schooler who is staying strong to avoid being prone to crying. Manaka is shown to have feelings for Tsumugu Kihara and is highly dependent on Hikari and Chisaki Hiradaira. As time passes, she starts to become more independent. After saving Akari Sakishima during the Ofunehiki festival and falling into the sea, she enters hibernation and takes on the role of the sacrificial maiden for the Sea God. After the time skip, she is found in the middle of the graveyard of Wooden Maidens near Shioshishio and brought to the surface while losing her Ena. She wakes up one week later and ends up staying with the Shiodome family. She had also lost the ability to fall in love as a result of leaving her post as the sacrificial maiden. Later, it is revealed that she has been in love with Hikari all along but decided to keep it a secret as she knew about Chisaki's feelings for him. In the last scene, Manaka's and Hikari's feelings are clear to be mutual as they look on to the sea together.
