Hidaka Takeshi

He is Arisa's husband and a freelance designer. Although he is a freelance designer, he only works on Arisa's company's website and other small jobs.

He is an all-around good househusband, but he is very lenient with his daughters, which has caused them to grow up to be a bit selfish, which is a recent problem for him.

While he is enjoying his hobby of fishing on this trip, his beloved wife and children are being corrupted.
