I saw the one other entry for this on Nyaa was from 2011 and appears to have long since died. So I've uploaded the .mp4 (RAW - though there's really no dialogue anyway) version. I won't be seeding this forever. "Animator Sakamoto Shouta (坂本渉太) conceived, designed, animated, and also composed music for the above animated short, which the anime studio Gainax began featuring on its official website. The video mimics the popular sentai genre, with five young people transforming into a costumed superhero team." ~ MAL MAL Entry: https://myanimelist.net/anime/13311/Henshin_Gattai_5_tsu_no_Atsuki_Tamashii
