I've probably already said it, but tracing (and heavily modifying) from an ad - those things that are forced into our faces whether we want them or not - is simply not a bad thing to me. When I had to be an ad copywriter, if someone had stolen my work i would have just laughed, and if they had put it into a story like Prism, I would send them fan mail. Honestly, I always thought of this nonsense as his karma for his hentai loli comics, full stop. It's just a pity Prism got caught in the crossfire.
Yea i was very disappointed and put-off when i researched and tried to find any other creations by this author years ago and came to find the loli hentai catalog that they had.
