The 6th Anniversary song is too emotional

The melody really feels like end credits, it's super emotional, and the 3DMV is also really emotional, so I want everyone to watch it. I got a new smartphone, and it's the 6th anniversary, so I'm returning to ProSeka after about a year. My fingers aren't what they used to be, and I'm truly amazed by my past self's skill. As usual, Unlimited. Looking forward to the matches m(_ _)m
