Mashiroiro Symphony HD -Love is Pure White-

Kagamidai is a blend of two towns, old and new.
Each has colorful scenery and colorful people… but it’s as if the two are painted in completely different colors.

Shingo Uryu is a normal young man from the new side of town, but the academy that he attends is about to be integrated with a venerable edifice of the town’s older side—the prestigious Yuihime Girls Private Academy.
Thrust into a combined class to help test the upcoming merge’s effects, Shingo begins commuting to Yuihime… and his life starts to change.

A somewhat strong-willed young woman who’s firmly against the schools coming together…
A girl who aspires to become a maid due to her mother’s influence…
A young lady as gentle as she is mysterious…
His one and only little sister…
The time he spends with these young women begins to lend his humdrum days a different hue.
