Suzuha Amane

Suzuha Amane (阿万音鈴羽, Amane Suzuha) works part-time for the landlord of Rintarō's flat and is on a search for her father in Akihabara. She enjoys riding her bicycle and appears to be at odds with Kurisu.

She is in fact a Time Traveller from 2036 who, using the guise of John Titor, seeks to prevent SERN from creating a Time Machine that will lead to dystopia.
