DIY♡ (Dance In Yourheart) is a Hello! Project unit consisting of Yajima Maimi, Tokunaga Chinami, Natsuyaki Miyabi, Nakajima Saki, and Iikubo Haruna. The group was first formed at Hello! Project Tanjou 15th Anniversary Live Summer 2012 ~Wakuwaku Natsu no Fan Matsuri!~.
DIY♡ was formed in July 2012 when it was announced that they would perform the original song "Forefore ~Forest for Rest" at Hello! Project Tanjou 15th Anniversary Live Summer 2012 ~Wakuwaku Natsu no Fan Matsuri!~ and Hello! Project Tanjou 15th Anniversary Live Summer 2012 ~Kitakore Natsu no Fan Matsuri!~. They were formed alongside the group Peaberry to be part of Hello! SATOYAMA Life, a movement that aims to remind Japan of their beautiful countrysides and the need to conserve them. The group's name is a common abbreviation for "do it yourself", but in this case is meant to mean "Dance in Yourheart".
Tokunaga Chinami and Iikubo Haruna's colors were changed from Yellow and Pink to Purple and Yellow during the concert to match Iikubo's color change in Morning Musume.
