While living in Auckland in 1989, a teenage Aru worked in a factory making biscuits.
"I spent most of my pay cheque on comics."
He said the books still played a huge part in his life.
"I couldn't read as a kid - and so I learned through my love of the stories in the books. It made me want to learn."
The tales also provided escapism.
"I was a difficult one growing up. They fed my imagination and taught me a moral code."
So, what gems lies inside Aru's counter?
"My favourite is Spider Jerusalem, a futuristic journalist. The artwork is amazing and I met the US artist Darrick Robertson in Auckland last week." He grins as he holds up a signed and sketched copy of The Boys.
Aru's favourite character was The Punisher, an anti-hero who featured in the Marvel Comics line-up.
These days, trending comics include The Walking Dead, Gotham, The Flash, Arrow and Agents of Shield - all made popular by current TV series.
Comic Trade is only open from 3pm to 7pm from Tuesday to Friday, and noon to 5pm on Saturday. It also houses a room for board gamers.
