On Tuesday I went over to Roppongi Hills and discovered the mutant spider still dwells there. I got there fairly early and there weren't too many people around. It took an infuriating amount of time to reach, though. A good 20 minutes to Roppongi on the Oedo line, a long climb through the station and finally a good walk to the actual site.
Still an impressive location, but I guess I've moved on. It wasn't what I was looking for anymore, certainly not alone at any rate. Gomen nasai.
