is a manga series written by Sachi Oshimizu. It was later animated into a 3 episode anime OVA series in 1996. Both the manga and the OVA have been licensed by Media Blasters for distribution in the USA. It follows the story of a humanoid created by a robotics expert named Dr. Otoi for his grandson, Nobuhiko. But in the process of writing and applying the programming, an unfortunate mishap took place when Nobuhiko sneezed. Now, whenever Nobuhiko sneezes, the humanoid (named Signal) transforms from a temperamental adult robot into a chocolate-loving baby version of himself. Despite this, the days spent with the Otoi family are usually fun. Animals, people, and robots all live in harmony. One day, Signal is attacked by Pulse, a robot created by Dr. Otoi some time ago as Signal's prototype. Pulse is incredibly nearsighted, but makes up for what he lacks in vision with firepower. Dr. Otoi's mysterious rival has packed him to the brim with amazing weaponry, with the intent of stealing the Doctor's most recent technology. Characters Signal The namesake of the series, Signal is the newest HFR (Human Form Robot) to be created by Professor Otoi. He is unique because of the MIRA and SIRIUS technology in him, which sometimes makes him a target of those wishing to steal his data. He is programmed to be a fighter and an older brother to Professor Otoi's grandson, Nobuhiko. Due to an accident in the lab during his creation, when Nobuhiko sneezes, it transforms Signal into a much smaller version of himself. He is referred to as 'Chibi Signal', is very hyper, and adores chocolate. Nobuhiko Otoi The grandson of Professor Otoi. Signal's 'little brother'. Because Nobu interrupted Signal's programming by sneezing, he ended up causing a glitch in MIRA. Every time Nobuhiko sneezes, Signal transforms into a 3-year-old chibi signal. Nobuhiko's grandfather. Mini Signal Chris Sine The one and only super smart robot scientist" as she would say. She's somewhat loud and obnoxious but yet still a likeable character. However despite her claims of being such a genius and beautiful robot scientist, Kris is a bit of a flop. Her robots often end up failing, or going berserk, or just simply getting smashed by Signal. But she wishes to create a super robot more powerful and impressive than any other, despite her failures. She soon becomes the apprentice of Dr. Otoi and appears
