The Day Tomobiki Stood Still.

Lum was furious. Not an uncommon state when you're a short tempered alien girl 
trying to keep your girl-chaser of a fiancee in line. She kept patroling over 
the streets of Tomobiki, trying to locate Ataru. It was fairly simple : just 
follow the trail of angry girls. The shouts of "Hentai!","Sukebe!","In your 
dreams, moron!" and "I shall make you two for that, Moroboshi" were usually good 
hints too.

A few meters below the wanabee Casanova was using his straightforward approach.
"Eh Miss ! Over there ! Wanna go on a date with me ?"
The only response of the girl was too speed up, but Ataru Moroboshi didn't grasp 
the concept of "giving up".
"Wait, baby, if you can't right now, just give me your adress and phone number, 
I 'll..."

"DARLING! Stop harassing other girls-tcha!"
With the experience of someone well trained to this kind of confrontation, Ataru 
calmly faced his girlfriend.

"I'm not harassing anyone, I'm merely offering a beautiful girl the opportunity 
to spend some time with me. Right? Miss..."

But when Ataru turned back, the girl had already vanished. Few girls liked to be 
seen hanging around with the most lecherous being in the universe, and everyone 
in Tomobiki stayed the hell out of ground zero when Lum was angry.
Except Ataru.
"Darling, i don't understand! Why won't you stay with me-tcha?"

Ataru loved this part of the game. His mind was racing: looking for  ways to 
escape the incoming punition, searching for the words that would trigger it at 
the correct time. Of course, he was probably going to be fried by Lum anyway, 
but that was part of the game. Besides he had develloped a lot of resistance to 
electric shock. Maybe he was a masochist but he just loved to make her angry.
And God! was she cute when she was angry. 

"Come on Lum! Those girls need me.Don't be egoistical, you 'll have to share 
me..."

That was it. Ataru could see the arcs of electricity forming all other Lum's 
body. He ran away. Fast.But this time he didn't make it.

"I don't SHARE !"
With this cry, she filled the street with electricity bolts, a good proportion 
of them hitting their intended target. With a cry, Ataru collapsed.
Lum flew to the charred remains of her boyfriend. But the one and only phoenix 
of Tomobiki was already rising from the ashes.

"Tsk,tsk,tsk! Lum ,can't you do better than that? I hardly felt a tickle."

If Ataru had been lax enough to kick himself he would have done it. He should 
have known better than to provoke her again.
He closed his eyes and waited for the second impact. Nothing. He waited a little 
more. Still no sign of any Divine Retribution. Filled with hope, he looked at 
the place were Lum stood a moment ago. She had left.
Ataru sighed in relief,maybe he won that one after all.

Ataru looked at the street, something was weird but he didn't see what.
Sudden realization , by the mean of a small rock, struck him.
The wind.
The street was in a middle of an ascending current of wind, and small objects 
floated in mid air. Ataru, guided by an understandable curiosity, looked up.
There she was. Very angry,very good looking and very blonde.
Ataru didn't notice the blonde hair,rising to the skies, defying gravity. 
He was gazing at the huge energy aura that surrounded Lum.

"So Darling, You wanted to see better-tcha?"
"Wait, Lum-chan, I didn't mean to..."
Lum joined her hands and brang them to her side.
"Please, Lum-chan, don't do anything stupid...*oops*"
Definetly not the best choice of words.
"Grrr! Darling no baka! Just you wait! KAA..."
An energy ball appeared between her hands.
"Woooo! Ok,I promise not to chase girls today!"
"...MEEHAA.."
The energy ball was now the size of a watermelon.
Ataru understood that it was time for a great sacrifice.
"For a whole week!"
She was clearly not listening. Ataru quickly recommended himself 
to the  7 Gods of Luck, expecially Benten-sama. 
"...MEEHAAAA"
 Nothing. Lum was still helding back the energy-ball, now yellow.
Ataru laughed, he should have known she wouldn't dare.
"...-TCHA!"
Tiger stripes appeared on the energy ball and Lum threw her hands forwad. A 
black and yellow energy beam struck the ground a few meters from Ataru. After a 
deafening explosion, a huge cloud of smoke filled the sky. Exhausted, Lum waited 
for it to go away. Below was a huge crater of destruction. Buildings had 
collapsed, a crowd had gathered near the ruins and in the middle of this mess 
was Ataru.

All anger gone, Lum rushed to the motionless form of her boyfriend.
Slowly,painfully, Ataru came back to his senses.
When he opened his eyes, Lum was staring at him, concern all over her face.
"Is my Darling ok-tcha ?"
Ataru was too bewildered to answer.
"So, Darling, was it powerful enough-tcha ?" she continued.
She was too tired to really sound sarcastic.
"Lum, we 've got to have a serious talk about your new friends from Saya"
