signal
The main character and namesake of the series, Signal is the latest HFR (Human Form Robot) created by Professor Otoi. He stands out due to the MIRA and SIRIUS technology integrated into him, often making him a target for those who wish to steal his data. Signal is designed to be both a fighter and an older brother figure to Professor Otoi's grandson, Nobuhiko. An unexpected lab accident during his creation has given Signal a peculiar trait: whenever Nobuhiko sneezes, Signal transforms into a much smaller version of himself. This miniaturized form of Signal is affectionately called 'Chibi Signal', and he becomes very energetic and has a love for chocolate.
