[Para 2]
Every now and then something bad would happen. Others would come by, seeking something from the forest without the intention of giving back, or some disease or poison would be leaking into the forest. It was Raijin's job to take care of the forest, and because he didn't know how to deal with all these foreign things, he sometimes had a really hard time doing so. Trial and error was his only hope at saving the forest- and thankfully he was able to mix up the right concoctions and antidotes for all the poisons and diseases that came through, but not without some losses. Trees died and animals passed on, but Raijin stayed strong. When humans came by to take wood or plants from the forest, Raijin was finally forced to show himself to them, for how else was he to deal with such a problem? Approaching them, he proclaimed
"It is my duty to protect the forest, and those who live within.
Anyone who dares to attack it or take without giving back or asking will suffer accordingly."
At first they seemed astounded that there was something- a creature resembling a flit, no less- that spoke to them and defended the forest against them, and then they just laughed, taking what they wanted.. but not for long, Raijin vowed.
Well, that's the last time they would be laughing. Raijin returned to his mountain after that, letting his body curl inwards as he shrunk down to fit in the large opening to the willow tree, closing his eyes and letting his body and mind connect to the nature that surrounded him. The humans punishment would be left up to the forest this time- and oh did they have a nasty surprise for them.
The next morning the humans returned. Raijin was sat near the edge of the forest, peering out at them. As they approached, he let his body grow larger and climbed to the tops of the trees, grasping a bundle of different plants in his jaw that he dropped upon the humans as they walked within throwing distance of said plants. He watched as they looked around in confusion before they started screaming, red blotches covering their skin in every place that the plants had rubbed up against. Their skin on fire, itchy, and drying out, the humans ran away and left whatever they had been carrying. Raijin swooped down to gather everything left on the floor, floating lightly above the ground. However, as soon as his body left the forest his heart started aching, being tugged back towards the forest. Raijin quickly turned back towards the forest, his body still enlarged so that he could carry each item the humans had left, dropping it all in a small pile near the willow tree as he reached it, his body then shrinking back to the size he was most comfortable in, his paws touching the ground lightly as he ceased his floating.
From that day on, though- humans no longer took without giving back, so really it was all worth it. Occasionally there'd be another issue with them, but Raijin knew their ways now, and had learnt to speak and understand their tongue rather well, so communication was no problem for him and he dealt with and grew more knowledgeable with every problem, often coming up with creative solutions, his pile of "junk" or "trophies" growing each time. So really, it was a win-win for Raijin. His hoarding tendencies and the forest ended up both sated, and the peace would continue.
