IMO Hitorijime flopped cause:
- the song is average, I don't think people bought multiple copies this time
- no handshake event
- the single got delayed because of Morning Musume's new single, all mag articles came out way before the single and their MF appearance got delayed too
- The concert DVD coming out a week after the single and overall Viyuden has released too much stuff lately, fanboys just can't afford to buy everything.
- no huge Rika buzz, Ajisai was released right after she graduated so of course it got promoted a lot
I think UFA spent so much time & money promoting the latest Morning Musume single that they didn't give that much attention to Viyuden this time. When Ajisai came out Viyuden got promoted more and there was the concert tour too so the hype was huge.
So hopefully their next single will be a fast song and UFA will give them more attention. Another handshake event wouldn't hurt them either. Fortunately it's coming out right before their Fall tour so there will be more hype. However I think it's coming out too soon after Hitorijime. Hitorijime was released only a week ago and their next single is coming out in only 6 weeks. Anyway their sales better improve, I think Hitorijime is the 2nd worst selling H!P single of the year so far (only MKB's Eros has sold less).
NEWS:Viyuden will perform at Rakuten Eagles' game on 8/21. After the live performance there will be a handshake for those who have bought Hitorijime single/purchased 1050yen worth of Eagles goods. Viyuden also appears during the game but I'm not exactly sure what they are doing.
