How nostalgic. This is very much like Doraemon/Ding Dong. Almost exactly the same.
I haven't yet found out the names for some of the characters, but here they are (description followed by name):
- Main char = Tarou
- Fatty = Hihiyama
- Girl = Miki
- Boy with short hair and spikey bangs (whom I tentatively dubbed Frankie due to the uncanny resemblance to Frankenstein's hair) = Rakkyo
The stories are only like four pages each, real short. So tons in one volume.
