"Losin'" is Yuna Ito's 5th single.

Losin is the Japanese ending theme to Lost Season 2 that airs on AXN.

For those who bought both singles, they would receive a special invitation to Yuna Ito's first tour, an invitation-only tour called "Yuna Ito's 1st Invitation".

This song features both English and Japanese lyrics.
