Winter lake

Naoko Tsuda used to stay at Lake Yamanaka during the summer vacation when she was a child.
There are lots of Naoko’s memory at the lake, swimming in the lake with her sister and adventuring the mystery forest.
Part of this artwork drawn with the stylus which gave her a hint to master this technique. Naoko uses the stylus to draw on the white paper to make the groove on the paper. Naoko spent lots of time to practice the technique and becomes the unique point of her art. The advantage of using the stylus is able to draw the sharp white line but still, the disadvantage is not able to erase after drawing the line. Are you able to find out the part drawn with the stylus?
During the unpopular winter morning, there are shadows wear the mantle passing the lack beside the forest. Who are they? Maybe they are senility residents spelled by the magic or maybe they are the wizards. The person who knows this answer is the lord of the forest which changes itself to a small creature. It wanders around the frozen forest without anyone notice everyday morning.
