Mamoru Urakawa

Mamoru Urakawa (浦川まもる Urakawa Mamoru) is a character from Mega Man Battle Network 3. Like Hub Hikari, Mamoru has the heart condition known as HBD. He has been hospitalized since he was three years old, and remarkably survives what most people would not. He is the operator of Serenade.EXE, the UnderKing and current ruler of the Undernet. He is the son of Kimie Urakawa, owner of Yoka Inn, and the nephew of Tamako Shiraizumi.

Overview
Mamoru has deep-black eyes and brown hair, and wears a yellow long-sleeved shirt with tints of orange running down his collar into the bottom at the middle and at the sleeves, yellow pajamas with orange edges at the ankle portions and brown slippers with white socks.

Mamoru tends to be secretive for the most part and for this reason not much is known about him. However, despite his shy nature, he is actually a friendly individual who gets along with people in his own age group almost effortlessly; he quickly bonds with Lan on their first meeting, and it is heavily hinted in one of the late-game cutscenes he has also befriended Lan's other companions. On a few occasions however Mamoru can be prone to pessimism, at one point prompting Lan to comfort him with words of encouragement through narrating Hub's own experiences with HBD.

In many aspects, Mamoru is a more-than-meets-the-eye character in the series. An example of this is his frail condition on account of his HBD being countered by his status as the Undernet's administrator.

Game History
Yai falls down the loser chute following her defeat in the N1 Grand Prix, suffering a grievous head injury in the process. She ends up being sent to the Seaside Hospital for recovery, where she is soon visited by Lan, Mayl and Dex. After swearing to "sue Sunayama for all he's got" due to the incident, Yai complains of the boredom she is experiencing brought about by the length of her stay in the hospital and imperatively orders Lan to fetch some tea for her. Lan begrudgingly agrees to do so and sets off downstairs.

At the hospital lobby, a nurse approaches Lan and inquires as to the whereabouts of a wheelchair-bound patient named Mamoru. He denies having knowledge thereof but promises to search for him, putting Yai's request behind for the meantime. Not long after Lan heads outside and finds Mamoru at the beach, with the two making fast friends with each other. Their first meeting is cut short however when Mamoru suffers an HBD strike, forcing Lan to return inside the hospital to seek help. He is quickly sent back to his room for diagnosis, with Lan trailing right behind him. Because Lan's NetNavi, MegaMan.EXE, had originally been Lan's twin brother Hub and thus had died from HBD, the NetNavi immediately recognized the symptoms upon witnessing it. Mamoru recovers and Lan promises to visit him at a later time and returns to Yai, who impatiently asks him where he has gone.

Lan visits Mamoru at the beach on their second meeting as promised. After a few exchanges, the latter yet again suffers another HBD attack. Seeing this, Lan re-enters the hospital and finds Mamoru's doctor, taking him and a nurse to assist Mamoru. This attack lands Mamoru in the emergency room, but he expresses refusal against undergoing another surgery; his nurse tells Lan all three surgeries he has had previously undergone were unsuccessful. Mamoru has no hope that a fourth surgery can solve his problem, even though it is a new kind of surgery for treating HBD; upon hearing this, Lan provides Mamoru with encouragement by giving him the rare Battle Chip he wanted, IceBall M. Mamoru's condition gets worse three days later and he is sent to the emergency room for his fourth surgery. Three hours into the operation however the surgery is interrupted by Anetta who, disguised as a nurse, uses her NetNavi PlantMan to make the growth process of the Tree of Life malfunction and create vines throughout the hospital to render most of its facilities useless in order to find a TetraCode for Wily. After MegaMan defeats PlantMan, the Tree of Life returns to normal and Mamoru's surgery is successful.

Lan later on comes across the sinister source of the Undernet at a hidden elevator located past the hot spring at the Ura Inn; here it is revealed that Mamoru is the Undernet's administrator, much to Lan's surprise. Mamoru then explains his father's involvement in the Undernet's creation as well as the "Giga-Freeze" program, capable of subduing Alpha but can be dangerous in the wrong hands. Not long after this the two receive word that the SciLab has been infiltrated by none other than DrillMan.EXE, who after stealing Alpha therein, escapes via a distorted portal he himself had just created into the Undernet. Lan tends to the situation and Mamoru presumably stays behind to oversee his duties as the Undernet's operator towards resolving the crisis.

Mamoru (together with Mayl, Yai, Sean, Dex and Chaud) is seen comforting Lan on the Seaside Beach in the recent wake of MegaMan's apparent demise after the latter destroyed Alpha, thanking him for giving him the courage to face his disability as well as his companionship. He returns to Yoka after this but it is now assured he has been cured of his long-standing disease. A scene in the end credits further supports this which shows Lan giving Mamoru a PET, suggesting that he was well enough to NetBattle.

Despite his importance in both Mega Man Battle Network 3 and the Undernet, Mamoru did not appear in any games later installments although an e-reader card for the Japanese version of Mega Man Battle Network 6 called Mamoru's Get Well Gift (which gives the player a set of sub chips) was released, implying that he continues to remain in touch with Lan long after the events of the third game (and presumably well into series' epilogue).

Etymology
Mamoru is Japanese for "protect", and Urakawa literally means "inlet river". His surname is shortened as Ura in Japan, which can mean "reverse" or "backwards". Mamoru's full name in English literally means "(to) protect (an) inlet river", which is actually quite accurate given his status as the administrator of the Undernet and his attempts to keep it as a secret even among his friends, notably Lan. Urakawa might be also a reference to the Undernet, as in Japan it is called the "Uranet" or "Ura Internet". As the internet itself compared to a river of data, the Undernet is a flow of information underneath the main, superficial flow of information.

Urakawa is also a town in Hidaka Subprefecture, Hokkaido, Japan.
