How often is iOS Taiko no Tatsujin Plus stealing song debut from other games? Quite frequently, especially when you count today's new Popular Song Pack 21 (人気曲ぱっく21), which has stole Murasaki ver.'s thunder in featuring the awaited Assassination Classroom theme, among others in a usual-priced 600-yen pack:
青春サツバツ論 Seishun Satsubatsu-ron Assassination Classroom
イマジネーション Imagination Haikyuu!
桃源郷エイリアン Tougenkyou Alien Gintama
さくら Sakura (Ketsumeishi)
ごめんなさいのKissing You Gomen Nasai no Kissing You
And quickly we also do the first video here: Seishun Satsubatsu-ron has the medium-high difficulty set of 4/5/7/8. The 408-note Oni sees quite a few instances of longer clusters (5- to 7-hit) in condensed groups among otherwise quite sparse sections.
