Episode 31: Who Goes There?
(featuring Vampire Plant Keronia)
Goto, from the SSSP South America branch after 20 years returns to Japan to work with SSSP Japan The SSSP Japan officers are confused because he doesn't look to be over 30 which means he would have started working for SSSP at age 10 (I guess they forgot Hoshino, Isamu would was 12) but then he explains that 20 years ago his father was the SSSP member and the family had moved to Bolivia. Cap tries to light his pipe but his lighter won't light. Fuji offers match but it goes out. No one notices the look on Goto's face when he saw the lighter and the match.
