Asuka On Board (Easy)
アスカが乗ってるんだよ！ 初級
Asuka On Board (Easy) is a Battle Cats stage in The 9th Angel Strikes!. It costs 50 energy and sends 6 enemy spawn lines — led by The 9th Angel (Enemy) as the boss — against a 40,000 HP enemy base, and clearing it rewards 7,050 XP. Its enemies carry the Eva Angel trait, so cats that target it do the most work here.
