KoTenshi is a line of MSD size Tenshi dolls from Volks. They are made genderless and the body is like the Volks MSD boy body, only without genitals. Unlike most MSD, the KoTenshi have one normal H-01 hand (their right) and the left hand is a special KoTenshi-only hand.
They are sold as standards at Tenshi-no-Sato. Some are also released as limited editions at events.
