彼女が俺にくれたもの。俺が彼女にあげるもの。 ～KISS My Darling：めちゃ婚case3～

Mikado is a normal guy who longs for a harem and bringing happiness to all the girls in the world. Since this requires lots of money, he spends every day and night doing part-time jobs. His mad scientist and hikikomori imouto Tsubasa was worried about her dear brother neglecting his studies. So, she created the ultimate sleep-studying device Pandora to help him, resulting in him having lots of information from the net downloaded into his brain. At that time, a beautiful girl Carrot transferred into his class. After hearing her refined greeting, he knew from her name that she was the princess of a certain country. With her true identity suddenly made public, she became really close to him and his surroundings began to change. This is the third game in onomatope*’s harem-centric Mecha-kon! series. The concept is split into two parts: lovers and bride (family). It has a ‘family chat system’ WIRED, as well as a ‘girls talk scene’. Not only are the heroines available, but there’s routes for sub heroines as well. [From Hau~ Omochikaeri!]
