Haruka is not a part of any of the events in this game. Lan responds by jacking in at the Waterworks and stopping IceMan, who was infected by the Zero Virus, from disrupting the Waterworks any further. When she gets there, she is informed that the Waterworks computer is not working. Haruka goes to the Waterworks to submit a complaint about the water at her home not working. Haruka also gets wrapped up in an incident at the restaurant from the Government Complex while going to dinner.

Later, Haruka is the first one to let Lan know that the water in the city is not working, leading up to the events that happen at the Government Complex. They battle, and MegaMan emerges victorious.

MegaMan explores further and finds FireMan, Mr. MegaMan uses a WaterGun Battle Chip to cool down the flames a little bit in the oven. The repairman reveals himself as an agent of World Three, Mr. After the repairman leaves, she begins cooking only to have the oven explode again and start on fire. She tells Lan to go to his room while this work is being done. In the first game, she calls a repairman to check her oven after several ovens started exploding in the city. Oftentimes in the games, she is put in danger by Lan's enemies. Since her husband is constantly away from home on expeditions, she sees Lan as her main priority in life. Haruka mainly stays home to take care of Lan Hikari, and doesn't seem to have a job. Her skin is light tan, and she has brown hair.

She wears maroon sandals, a green dress, and a purple shirt.

However, in the anime, she does not nag as often. In the games, she is always nagging Lan to do his homework and get ready. She is a good cook and has no trouble asking Lan to help delete viruses around the house, especially in the kitchen. Haruka is a stay-at-home mom who worries over Lan and his wild exploits.
