Sunny wants to go to DoKomi

Hello, I am a young Ukrainian who enjoys Japanese music and culture (not a weeb, I promise). My favorite Japanese group, MeseMoa., are coming to Europe this year, they will be performing at DoKomi festival in May in Düsseldorf, Germany.
While it is quite far from Ukraine, this is the closest to my location they have ever been, so I really want to go there and see them for the first time at their first ever show in Europe.

It is extremely important to me because MeseMoa. have been inspiring me for two years now and I am grateful to them for making me smile every day and motivating me to work hard with their own hard work.
In particular, MeseMoa. have motivated me to continue my Japanese language studies and to set up a blog where I translate their tweets and other information for their foreign fans who are having trouble understanding Japanese.
I am currently a full-time student and can only work during weekends, so I am experiencing slight financial difficulties. What I mostly need help with are flight and accommodation expenses, as I already own the ticket to DoKomi itself.
The 300$ point I set only includes ~250$ for flight expenses and the currently unknown price for making a special biometric passport (presumably 30~40$).
However, any income is extremely valuable and I will be very grateful to anyone who helps me get closer to my dream, even if it's just 1$.
