Fidelity to You Alone (feat. Apple)

yamitsuki's latest single "Kimi-sen Fidelity (feat. Apple)".

This track is part of the ongoing series by yamitsuki, a music project led by YouTuber Akecharu and composer Zero, built around the concept of creating "addictive music."
Known for collaborating with different vocalists for each release, this time they feature Apple, a member of the popular YouTuber group PKA.

While their previous collaboration with Apple (feat. Ochanko Mate), "mew! mew! mew!", explored a cat-themed concept, this new track shifts to a dog motif-expressing a more straightforward and devoted form of love.

The song was initially previewed as "Apo no Uta (Working Title)" through a collaboration with Famima Print, where it surpassed 2.5 million total plays across UGC and short-form video platforms.
Now gaining traction across social media, the full version continues to expand its reach.

Combining yamitsuki's signature catchiness and addictive quality with a deeper thematic contrast, this release highlights a new dimension of their expressive range.
