His casual clothes consist of a pink long-sleeved shirt with a white heart pattern on the front, and blue jeans.

Susumu is the world's highest ranked Driller, given the title "Mr Driller", and is also a member of the Star Trigon Team. Susumu is a very courageous young boy, and very kind and sweet. Though, he can be a bit careless and an airhead. He lives in a pink house shaped like a Pooka with his dog roomate Puchi in Edogawa, Tokyo. Susumu is the 2nd youngest character in the series, along side with Taiyo and Puchi. Susumu is slightly younger than Anna by 2 months.
Susumu's favorite food is rice cakes stuffed with bean jam. His favorite hobbies include digging in ancient ruins, and ice sculpting.
