It’s a nostalgic piece that makes you unable to help but think of friends or someone you once loved who are far away.

It’s a song by Seiko Oomori, a singer-songwriter from Ehime Prefecture, released as a single in 2015.

It was written as the ending theme for the anime Food Wars! Shokugeki no Soma.

The lyrics, which recall memories of playing with Sacchan and reflect on how she’s doing now, feel somehow bittersweet.

I can’t help but find myself listening to it and thinking, “Come to think of it, what is that person up to now…?”

Seiko Oomori, a genius at portraying the messy depths of human emotions and dramatic mood swings in her lyrics, resonates with many young women.

Orionza is a winter ballad she released in 2017.

Listeners have praised the song with comments like “I found myself in tears,” “a bittersweet yet hopeful track,” and “it suits winter perfectly.” The highlight is its lyrics: they’re compelling in the way they empathize with people despairing over their current situation and encourage them to walk toward hope together.
