Final Round (Hard)

Final Round (Hard) is the last stage in Sophomore Summer like all other levels in features Grim Hat (Enemy) Unlike all the other levels, the Grim Hats here are buffed. Beat this level and you'll get Akio Yabe (Rare Cat). The chance to get him is guaranteed so you don't need a Treasure Radar.

Strategy
Final Round (Hard) is fairly easy compared to most of the other Collab. events so this shouldn't be a problem unless you're Cats are fairly weak. True Forms for some Normal Cats are recommended like Macho Legs, King Dragon and/or Jamiera Cat to make the job easier when fighting this stage. Ramen Cat is advised because of his high health but you don't need a TF for any Rare/Super Rare/Uber Super Rare to beat this. If you are a beginner, this level may be slightly challenging.

Lineup: Macho Cat, Tank Cat, Brave Cat, Sexy Legs Cat, Giraffe Cat (Cat Army combo), UFO Cat, Whale Cat, Dragon Cat, Mythical Titan Cat and True Valkyrie Cat/Crazed Bahamut Cat.

For beginners, if you don't have Bahamut Cat, bring True Valkyrie Cat to be a substitute. Though here, even with a Level 20 Crazed Bahamut, you can't one-shot a Grim Hat so this level may be somewhat tough unless you have Crazed Bahamut. If not, you have to rely on spamming to get the job done. This is the Lineup for Non-Gacha Cats. There are some other options out there if you like using Rares/Super Rares/Ube Super Rare. Masai Cat, Paris Cat, Magica Cat or any other Cat that can deal with White enemies like Diabolical Gao or Shadow Mitama can wreck this stage but you can cheese this stage with a solo Awakened Bahamut.

The battle starts off with some buffed Squire Rels before the first Grim Hat spawns. Gory also appears but isn't very frequent so it's not much of an issue. Get out Brave Cat/Ramen Cat/Masai or Jiangshi Cat before the Grim Hat spawns, after Grim Hat spawns, stop sending these units and get out Wall Cats and Macho Cats and upgrade your wallet and get it as high as possible before sending out you're main attackers. Only do this if you're Cats are weak, if not, then keep up the spawning. Take it easy when spawning Cats in the beginning because you don't want to start the wave of Grim Hats when True Valkyrie Cat/Crazed Bahamut Cat/Uber isn't on the field.

The moment your Cats hit the base, the wave of Grim Hats will spawn. Spam everthing you have because Grim Hat has a single attack and all of them have been synced so you can overwhelm them. Another one will spawn quite a while later so try finish of the wave as quickly as possible.

Once you defeat the wave and/or (depends) beat the extra Grim Hat, no more will spawn. If you finished off the horde without the extra one appearing, the extra Grim Hat will still pop up at some point though it may be trying to hit your Cats while you're attacking the base (that all depends how quickly you defeat the horde). Spam everything and the Power Pro. Collab. Rare Cat Akio Yabe is certainly yours!
