2006. Skirt Hirari
2007. Keibetsu Shiteita Aijou
2008. Oogoe Diamond
2009. RIVER
2010. Sakura no Shiori
2011. Kaze wa Fuiteiru
2012. UZA
2013. Koisuru Fortune Cookie
2014. Kibouteki Refrain
2015. Bokutachi wa Tatakawanai

2010 is my favourite year of releases so it was hard to choose but I chose Sakura no Shiori based on the whole single concept (PV, B-sides). Later years are hard but in the opposite way, I don't have a strong draw towards many of them.
