Sumikko

Hikaru's one true friend! Growing up, this playful pug was the only one Hikaru could count on. When she moved to a new high school, Hikaru was afraid that she'd never see Sumikko again, but the faithful friend tracked her down. Now, Sumikko lives in the school's storage shed and is cared for by Yasukuni. (source: http://www.gocomi.com)
