Mikuru Katsuhara, often called Micchon or Mi-tan, is a core member of the Eden of the East entrepreneurial group. Her exceptional technical skill shines as the developer of the Eden system's advanced image recognition software, the technological cornerstone powering the group's activities. This software enables users to identify objects and people via mobile devices, harnessing social networking data to deliver detailed information. Characterized by pronounced shyness, Mikuru withdraws in unfamiliar social situations but becomes notably open and direct among close acquaintances. Within Eden, her familial bond as Kazuomi Hirasawa's cousin solidifies her trusted status. Physically, Mikuru possesses brown hair typically secured with a pink hair clip and hazel eyes. Her standard attire includes a white shirt with blue sleeves featuring the word "earth," dark blue or purple jean shorts, dark pink tights, and white boots, occasionally layered with a blue coat. During *The King of Eden* events, Mikuru actively aids the group's search for the missing Akira Takizawa. She receives Saki Morimi's email confirming Akira's location in New York, contributing to the team's response. Her expertise proves critical when accessing and analyzing the vital Seleção database. However, Daiju Mononobe's cyberattack forces the group to temporarily shut down the Eden system to prevent further compromise. Mikuru's background as a programming prodigy underpins her integral role in Eden's technological initiatives and collective objectives. Her interactions remain primarily professional, focused on maintaining system integrity and supporting the team during high-stakes situations.
