Berryz�Koubou's newest single "Heroine ni Narou ka!" ranked #1 on the Oricon Singles Daily Chart on March 6th. The single jumped to 1st place from it's 9th place ranking on the previous day, giving the girls their first #1 on the chart.

"Heroine ni Narou ka!" was released on March 2nd and it beat out other big name artists who released singles on the same day (Akanishi Jin's "Eternal" at #3, No Sleeve's "Answer" at #4, Porno Graffitti's "EXIT" at #6, and IDOLING!!!'s "Yarakai Heart" at #9), as well as AKB48's "Sakura no Ki ni Narou" (#5) and Arashi's "Lotus" (#2), which were released earlier.

Berryz Koubou's last 11 singles have all ranked in the top 10 on the weekly charts, and it's looks like "Heroine ni Narou ka!" will extend that record. Congratulations to Berryz Koubou for this achievement.
