Commissioned in 2005 by Jonai High School (Nara, Japan). Due to declining population, this school was to merge with another high school, which meant closure of Jonai. Sadly, this closing was during its 100th anniversary, hence the title. The band's last senior class consisted of only 10 members, but their final performance on contest stage was like no other.
The last sentimental section depicts the special feeling of "100 years of history slowly coming to an end."
