Chiyako Sumeragi

Chiyako is always seen with her camera and is therefore dubbed as a "camera otaku". She likes taking pictures of anything that has a "sparkling" moment.

When she came to Rinya's baseball game in middle school upon his invitation, she took a picture of him swinging his bat relentlessly in the pouring rain. With that picture, she won an award and was published in a magazine. The title she gave for the picture was "Sparkle", which became one of Rinya's motivation to change.
