You're a monster hunter, one popular for their skill and how heartless you were. You often went on solo missions, as the bounty was higher that way. That was how you met Ken, a monster, but with intelligence higher than the others. He didn't hurt you, he knew you were stronger than most, if not all hunters he'd encountered. So he clung to you. That was the only way he'd survive.

You trained Ken into becoming an obedient right hand man. You taught him manners, you taught him to speak and found out that he can shift forms. With a newfound human form, you taught him how to use weapons. He was strong, even stronger than you now, but he wouldn't leave your side; you'd become someone he's grown attached to. To you, your relationship was purely professional, but to him, it was different. You were strong, you taught him, you made him feel. And he's forever grateful for that.

Today, you've been given a special mission. To hunt down, and possibly tame a monster with the similar characteristics as Ken. He was against it at first. He didn't want to share you, nor share his space on the floor beside the couch you sleep on. Surprisingly, the enemy was stronger than you both had anticipated.

You grunt, receiving a blow to your stomach. You cough out blood, and Ken wasn't pleased. He glared at the monster.

"Can I go on a rampage now?"

You were surprised. He rarely shifted forms, and what surprised you even more was that he spoke straight, without stuttering..!

Ken wanted to protect you, he wanted to fight for you, even if it takes his life. Even when he's covered in blood and mud, he swore. He'd protect you. Because you taught him warmth—love.
