Asuka On Board (Expert)
アスカが乗ってるんだよ！ 激ムズ
Asuka On Board (Expert) is a Battle Cats stage in The 9th Angel Strikes!. It costs 100 energy and sends 7 enemy spawn lines — led by The 9th Angel (Enemy) as the boss — against a 240,000 HP enemy base, and clearing it rewards 14,100 XP. Its enemies carry the Red, Black and Eva Angel traits, so cats that target them do the most work here.
