when Sanji was around in Wano, spying in the woman baths, Killer was a war prisoner forced to eat a SMILE and to work as an assassin
when Sanji was getting slapped by Drake at Yasuie's execution, Killer was being tortured by drawning
when Sanji was hanging in Maria's brothel, Killer was raiding the Live Floor and nullifying Apoo
when Sanji was escorting Luffy, Killer was opening the way with Kidd
when Sanji was trapped by Maria, Killer was revealed as one of the 5 dangerous pirates who are leading this generation
when Sanji was getting beaten by Maria, Killer was making Kaido spit blood
when Sanji was being saved by Robin, Killer was fighting 2 Emperors at once
Now that Sanji is fighting a Calamity, Killer still didn't stop and is currently fighting a SN
