Children's NAVI
From Serial Experiments Lain wiki
The NAVI that Lain Iwakura uses at the beginning of the anime. It is only featured in Layer 01. She checks her e-mail on it and finds one sent by Chisa Yomoda, a girl from her school who committed suicide.
The design of this NAVI is somewhat similar to the 20th Anniversary Macintosh.
Lain specially puts on a bear suit when logging in to this NAVI.
