アイドルマスター (iDOLM@STER) is a multimedia idol project created by Bandai Namco Entertainment. Initially starting with 10 idols of 765 Production in the franchise's 1st arcade game THE iDOLM@STER, now it has introduced many more idol agencies (876 Pro, 961 Pro, 346 Pro, 315 Pro, Million Lives (basically next gen of 765 AS), 283 Pro), developed games across all platforms, conducted plethora of concerts, live events, ect.
And the most important things, Million Lives anime doko, Bandai-san ?
I still remember that moment in 11th grade, when a close friend of mine introduced me to im@s. Unfortunately at that time I hesitated and didn't venture further. Not until 4 years later, when I watched that legendary Yakusoku performance in the 9th live that I felt something was ignited inside me.
Now that I think about it, although Shin Megami Tensei: Persona 3 was what motivated me to start the piano, it was iDOLM@STER (im@s) that really took me off.
TL;DR: im@s means a lot to me. There you go, 6-word summary.
