2021 April Fools Day Touhou Takeover

The 2021 April Fools Day Touhou Takeover was an event that took place on April Fools Day. It is the unofficial debut of Ultima Kuroninja, the Kuroninja of Earth 10000. During this event, Kuroninja TV uploaded 10 songs that appear to be covers for Super Sentai opening and ending themes, but because it's an April Fools Day event, the song covers are actually based on Touhou music.

The playlist for the whole event can be found here.

Background
Sometime in late 2020 or early 2021, Kuroninja of Earth 0 became a fan of the Touhou Project series and added Gensokyo to the Kuroninja Multiverse around late March. This got the attention of Ultima Kuroninja, the Kuroninja of Earth 10000, who instantly became a fan of Touhou. Ultima Kuroninja has the power to channel the abilities of anyone, as long as they exist in the Kuroninja Multiverse. Using his new power, he decided to make GarageBand covers for April Fools Day.

Trivia

 * This event would later lead to the appearance of Kogasa Tatara and Nue Houjuu in Kuroninja's 5th Anniversary Special, and later, Koishi Komeiji making an appearance at the end of Going the Extra Mile.
