>>92527262I've been to C101 and C104. limited goods in japan are war. melonbooks works for most books, but if your artist is small/non-local or they have event exclusive goodies, you'll need a whole strategy session. early entry is a huge resource, but you'll need to know a circle participant, staff, or get lucky with ticket lottery.
dealers hall is a lot of fun. there was a symphogear dj stage, professional gacha cosplays, some museum-style exhibits, and lots of official anime merch.
waiting in the summer sun for hours outside the venue sucked, but seeing world-class cosplayers and their sweaty tits out was awesome. I missed it but some interesting characters visited like notKiara and Chiitan. if you go once, I'd recommend winter comiket and the mogra NYE party after.
