Kaikan Denryuu: Hitozuma Kairaku Jikken Hasebe Yuka-hen

In an apartment building, a young boy named Azuma breaks into the room of Yuka, a housewife relaxing at home. Azuma possesses a unique ability called the "pleasure current," which sends a flood of pleasure through women with just a touch. He uses this power to seduce the housewives living in the building, aiming to become the master of a concrete harem.

Originally an introvert troubled by his constitution, Azuma hears the inner voice of a magician from another world, Rae, and realizes he is the magician's reincarnation. Following the voice, he learns to master the pleasure current and tests his powers on his beautiful neighbor Yuka.
