HIMEYUKA & ROZIONE'S STORY (Natsukashi Machi no Rozione), by Sumomo Yumeka. First published in 2005 and first published in North America in 2010.
PLOT:
Himeyuka was looking forward to living on her own until a weird little boy named Rozione shows up and makes her life a pain...at least, until she learns of his connection to her own past. Ayano is the heir to a Yakuza clan who hopes to distract herself from her arranged marriage by flirting with the cute boy at the local ramen stand. Shalala is a hapless half-witch hoping to increase her magic with the tears of a human boy, but things become complicated when she starts to fall for him. Finally, in a world where humanity only exists as the clones of a select few, two robot protectors come to terms with their own sense of humanity.
