Press release information is as follows:

"The first is the opening theme for Deaimon, a story set in an old confectionery store in Kyoto. The title is “Sumire.” The lyrics were written by Sakamoto herself, with composition and arrangement by Shigeru Kishida of Kururi, a Japanese rock band from Kyoto, matching the setting of the anime.

The second song is “Kotoba ni Dekinai,” the ED theme for the third season of the popular anime Ascendance of a Bookworm, which has sold over 6 million copies (including e-books). Maaya Sakamoto wrote and composed this song herself. The coupling track will be a studio live version of “Senri no Michi,” a song created to commemorate the 1,000th broadcast of Vitamin M, a radio program hosted by Maaya Sakamoto.

The limited first edition will come with a bonus Blu-ray containing the final day of Maaya Sakamoto’s Acoustic Live & Talk 2020 tour, which was held on November 29, 2020, at Zepp Tokyo.

In addition, two cover photos (limited first edition and regular edition) and a music video (short ver.) for “Sumire” have been released. The music video features Kento Ohgiya, who co-arranged and played the piano for Sumire."

For anime fans, Sakamoto's more recognizable leading roles include voicing Lunamaria Hawke from Gundam Seed Destiny, Shinobu Oshino from the Monogatari series, and Motoko Kusanagi from the Ghost in the Shell series.
