The Catbook
秒速５センチメンタル
The Catbook is a Battle Cats stage in Teacher! It's Spring!. It costs 75 energy and sends 14 enemy spawn lines — led by Le'boin as the boss — against a 40,000 HP enemy base, and clearing it rewards 10,575 XP. Its enemies carry the Red trait, so cats that target it do the most work here.
