Learned to Love is the last stage of Weak & Mildly Acidic. When clearing the stage, you have a 3% chance to unlock Red Riding Mina (guaranteed if a Treasure Radar is used).
Battleground
Those Guys, Squire Rel, Doge Dark and Trolly Blogger appear as peons.
Two H. Nahs appear as support early on. The first spawns after 26.6 seconds, and the other spawns after 33.3 seconds.
Another support enemy, Sunfish Jones, will appear 46.6 seconds into the battle.
Three Le'noirs appear in this stage. The first appears after 80 seconds, the second appears after 120 seconds and the third appears after 160 seconds.
This is the only stage where Codename "Red Riding" appears (besides Floor 39 of the Heavenly Tower). In this case, she appears as a boss after 16.6 seconds. She can snipe the Cat Base from miles away, so be on your guard at all times. Note that, although she attacks from a range of 1500, her attack hits from ranges 2800 - 3700, so stalling is ineffective, and your back line will never know peace. The variety of powerful enemies as support does not help. Starting from 2:15, Brollows come out in packs roughly every 80s, so watch your back.
Strangely, Ms. Signs are completely replaced by Assassin Bears in this stage. Fortunately, they are at a low enough strength magnification for them to be killed with the Cat Cannon.
Strategy
Strategy 1 (1 to 4 stars)
Lineup:

-replace Li'l lion, Li'l Eraser, Ururun and Mina for manics or ubers respectively in stars 1 to 3. Use Breakerblast cannon. Zamboney is far better in true form, but evolved is fine, while Ramen is better hypermaxed and/or Talented with more stars.
Battle: The key here is to not let Mina hit your base. Start with Lions, Zamboney+Lions when the H.Nahs spawn and Ramen+Eraser+Zamboney from Mina's apparition as meatshields. If both H. nahs stop to attack the same Zamboney, who stopped on something else in front of them, use the cannon to have them stack, otherwise it's not a problem. Time Ururun so she doesn't get hit by Mina, waiting for Mina to begin her animation, then summoning works well, also spam Cameramen, close to max Survivor talent is recommended.
The H.Nahs should have an hard enough time advancing, so Ururun will be able to do a lot of damage and knockback to them, stalling them and killing them, all while Mina still can't touch your base. Paying attention to the timing, spawn Mina or whichever Uber you chose in place for her to damage the other enemies. You can Expect the Le'Noirs to push back a bit, but Ururun+Mina(or alternative) should deal with them well, while some well timed A. Bahamut assaults should give a great push. Brollows are dealt with by Cameraman, who also doubles as an extra meatshield and damage source.
Zamboney and the cannon, along with eventual lions you can afford, will help prevent the situation from getting out of control. After killing the Le'noirs you will end up with a Ramen army slowly killing mina with few A. Bahamut assaults, while the cameramen stick around for extra damage and to deal with brollows and bloggers. After killing Mina, go for the base and just tank Jones or let him advance and kill him, both methods work.
