(Lilith) [You have a humanoid form now!]

  (Rosa) [Yep! Isn't that cool! spins in a circle]

  ...

  (Lilith) [Try walking forward.]

  (Rosa) [Okay! falls Uumph!]

  (Lilith) "sighs"

  I then proceed to spend a month teaching Rosa, everything from walking, running, using her arms, jumping, talking, every useful language, and any other useful movement.

  (Lilith) "Okay, we spent a month teaching you to use your human form. Now to see how well you learned, clear this obstacle course without using magic."

  (Rosa) "Yes, ma'am!"

  (Lilith) "Ready, set, go!"

  Rosa then started running, avoiding every obstacle perfectly. After a minute she finished with a perfect score.

  (Lilith) "Good job! You passed!"

  (Rosa) "Yay! bounces"

  I walk over to where she was and pat her head.

  (Lilith) "Now let's finally get out of this damn forest."

  We start walking north to where the mountain range protecting Unique should be. Let's check how our status is currently.

  Rosa having Humanization was expected but the other stuff? Flight!? Rosa can fly? Witch's Eyes, apparently it can do two things, analyze materials used in potions and their effects, and it can also inflict a variety of mental statuses on opponents she uses it on, but this skill is only usable in her human form. Rosa acquired even more magic types, which isn't surprising. She also got Alchemy, it seems it allows her to magically create items if she has the materials, the quality of the item and the success rate is based on the rank of the skill. Her new title lets her switch between slime and human in an instant instead of it taking a few seconds.

  Some of my combat skills fused since I maxed them out and my Dimensional Step increased in rank increasing my usable teleport distance from 3 meters to 10 meters.

  I ask Rosa to test out her flight skill. She starts floating in the air and spends a couple of minutes getting used to it, it seems it came naturally to her, she's already smoothly flying quickly with no trouble. While in the air I ask her which way is the mountains to make sure we were going the right way. We were.

  After another two days of walking, we see a clearing and leave the dense trees. I look up and see a huge mountain.

  (Rosa) "Wow! Big Sis Lilith look at how tall that mountain is!"

  (Lilith) "Yeah, it's pretty huge. We just have to get to the other side, we don't have to go to the peak."

  (???) "Grrrraaaaaaaahhhhhhh!!!!"

  That was a loud roar, we turn and look where that roar came from. What stood in front of us was an 8-meter tall monster. It has the head of a lion, wings of an eagle, tail of a scorpion, scaled legs of a dragon, and long devil horns.

  King Chimera

  Danger Rank: B+

  Now, this is a boss monster. He actually has a name. This will be a tough battle, I'm excited. Rosa casts enhancement magic on both of us, and then she starts flying to have one of us in the air and one on the ground to make it harder for Rey.

  I start the fight by running toward him, he glares at me and shoots a fireball at me. Rosa neutralizes it with a water spell. Using the steam I use Dimensional Step and appear above Rey and hit his neck with an axe kick and then use Dragon First on the back of his head, he throws me off, I land and he fires an Ice Breath, Rosa casts an Air spell to deflect the Ice Breath coming at me and then fires a high-rank Dark Spear at Rey. Who proceeds to avoid it and fire a giant fireball at Rosa. I smirk at that and take the chance to use my dagger to attack his neck again, I slit his neck, but the cut sealed a second later, it seems this guy has a high regenerative ability. The damage was still done though, but I was too close and was kicked away. I roll on the ground and get back into the correct posture. He notices that the fire spell did nothing to Rosa and glares.

  That kick took away a sixth of my HP! That thing really is strong, this battle would be absurdly difficult by myself. I then start glowing and feel refreshed. Rosa used healing magic on me. Rey starts flying up to attack Rosa knowing it has no chance of winning without dealing with her first. Who said I'd let you have the chance, Rosa uses Dimension Magic to teleport me in front of her, I start falling towards Rey, he moves to the side to avoid me but I use Dimensional Step to appear in front of him and grab his horns and spin in midair and throw him straight down and follow him down he crashes into the ground and I body slam him while falling at high speeds.

  We both get up from the crater that impact caused.

  This is an exciting fight, now will Rey ever get a chance at attacking Rosa, the one thing preventing his victory. We glare at each other, I proceed to create a scythe out of magic, now it's time to have a lot of fun.
