[Machine Translation] The long-awaited 3rd single of Aine Tomono! <anew>~new Return to the starting point, and the feelings that I want to convey once again~ Single with 2 songs. Aine Tomono's confident work celebrating her 6th anniversary! A permanent favorite! In "Mermaid Sanctuary," a song written by Tomono herself, she expresses her determination to move forward even though it is painful, and in "Colorful Days," a song about first love, you can feel her excitement and strong desire to color the future. The double A-side is a gem of positive expression of yin and yang.
