Aisha's home cooking.
Aisha simply destroying things.
The entire episode where an assassin from the Anten Seven poses as a tourist in order to try and kill Gene. Watching the poor guy's efforts keep getting derailed by unfortunate coincidences really was quite entertaining.
When Gene wakes up and sees Melfina not sleeping, he goes down to comfort her...in more than one way. Melfina fell asleep on Gene's shoulder, and as Gene's finger's slowly creep up Melfina's leg, Jim then comes and smacks Gene on the head with a frying pan. He then scolds Gene for being sleazy, AND THEN proceeds to cuddle with Melfina. This is made better when Melfina offered to sleep with Jim just a couple of episodes ago, and Jim was frantic to get away. Gene just got himself cock-blocked by an 11 year old.
When Gene first fights Suzuka, he makes her stumble by grabbing her sash. It comes off (Undoing her entire outfit in the process) and he proceeds to unabashedly sniff it, much to Suzuka's embarassment.
Bonus in that that very act (pulling the sash, not the sniffing) is used in old Japanese plays as a metaphor...and it's done by a guy who would never do that.
In the first episode, when Gene, Jim and Hilda are being chased by the Kei Pirates, Gene keeps pulling out successively bigger guns in an attempt to kill his pursuer...to no effect, since the pirate chasing him is using magic to protect himself.
