IMP. has announced that their third original album, PERIOD., will be released on December 14.

The album's lead track, "Period," is a winter love ballad produced by Kobukuro's Kentaro Kobuchi. Inspired by the period in IMP.'s group name, which is represented as a snowflake, the song tells the story of meeting someone so special that they could be one's final love.

This marks the first time IMP. has selected a ballad as the lead track for an album. The song will also be featured in a new commercial for HARIAS Medicated Cushion Foundation, for which the group serves as promotional ambassadors.

"PERIOD." will be available in three editions: a special edition, a first-press limited edition and a regular edition. The special edition, exclusive to the TOBE OFFICIAL STORE, will include merchandise such as a large fleece pouch and a lip case charm with a mirror.

To celebrate the release, IMP. will hold their first album release event, IMP. 3rd ALBUM 'PERIOD. SPECIAL SHOWCASE, on December 16 at Shibuya LOVEZ in Tokyo.

Approximately 4,000 fans who preorder the album through the TOBE OFFICIAL STORE will be selected by lottery to attend the event, which will feature performances of new songs and a talk session.
