I'm pretty sure it's denshin, not tenshin. The kanji used in it are 伝心, which transliterate to den and shin. This could translate to "devotion" but it makes a lot more sense to mean "dancing" given how frequently "dance" shows up in ending themes. I used the subtitles from this video as reference: https://www.youtube.com/watch?v=_PQG0esYIDE (time stamp is roughly 0:47)
I got this image off of Discord and Twitter. There doesn’t seem to be a Silver one however the magazine that this came from is TV Magazine September 2018 Issue w/ "Lupinranger VS Patoranger" VS Vehicle lite X-Train Gold Senko Kagayaki Ver.
