Only Brother Left

兄弟全滅

Only Brother Left is a Battle Cats stage in 300 Million Dead Molas. It costs 30 energy and sends 2 enemy spawn lines — led by Ayumi Manbosaki as the boss — against a 3,000 HP enemy base, and clearing it rewards 4,230 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
