I like how it looks like the little green guy just hitched a ride spontaneously. He looks so delightfully mischievous and fun-loving. The angel is both cute because of her child-like features, and majestic because of her statuesque posture and flowing hair.
it will be a fun comic, This moment will be during the time he was looking for Sesshomaru and found Sapphira who was also looking for Mimi Ru at the time they just sat around talking to each other. Because she does find him cute in his own way. She thinks its great dedication to serve someone for so long yet She happens to say "Jaken he treats you like scum.
Later on titled "Jaken's Confession!" He'll be bothered all day as he follows Sesshomaru here and there, he begins to think about Sapphira and how nice she was to him. One day he'll come out of the blue and says "Lord Sesshomaru... I Quit!" throws down the staff of two heads and then in a moment before he realized it could mean his death he starts groveling saying. "I'm sorry! a thousand times.
Haha, you're right! He would just keep walking with or without Jaken, though if Jaken really left, he would miss him, though he wouldn't show it... He'd probably go see where he is and if he was in danger or dead.
