I'm so happy!! Here's my story.
PART 1 - Ultima Weapon
I had fought Sephiroth many, many times, only getting past the first or second Sin Harvests (It was just so fun to fight him!). I went around all of the worlds, looking for synthesizer items. Ultima Weapon wasn't on my list, but I knew it was a synthesizer item. I thought that if I collected the stuff, it would be on my list. I already had more than enough to make it, but I couldn't figure out why they weren't putting it on the list. I finally tried buying everything already on the list, and it worked! There was Ultima Weapon! Problem is, after I bought all those items, I didn't have enough Thunder Gems. I went to the Tarzan world to look for White Mushrooms. First try, in the campsite area, there were White Mushrooms! I tried only using thunder, waiting until they wanted me to, but sometimes I made a mistake or got impatient. I had to leave the area and come back, hoping for more White Mushrooms, and to my delight there they were again! Same thing happened, and I had to try again. I only needed one more. I came back, and there they were AGAIN! Third time in a row! I got everything I needed. I went back to Traverse Town and bought me long searched for Ultima Weapon. It felt so good to have my main goal (at the moment) completed!
PART 2 - Extra Helpers
I had gained many levels on that quest and had achieved level 83 (around 10 levels higher than last time I fought Sephiroth). I had also attained advice from another, more experienced videogamer: A handy way to avoid painful Sin Harvests that you can't get to in time is to just use Strike Raid. It will interrupt him from casting Sin Harvest. Another thing that helped me was that before, I never used my items, which killed me many times in successful Sin Harvests. Now that I was getting seroius, I got rid of that personal rule.
PART 3 - Close
That night, I fought Sephiroth. I got extremely far! I was into his green health bar when he hit me with an unexpected Sin Harvest, and I fumbled with my items. He got me. I lost, but I was so happy that I had come so far!
PART 4 - Far More Success than Expected
The next day (today), I decided to visit my old buddy, the Ice Titan (<-Sarcasm). I hadn't fought him in a while, and I hadn't beaten him. The extra leveling really helped, and I think I had gained more personal gaming experience, as well. I beat him fairly easily!
I stared at the screen as the two-inch ice monster scrambled out of sight. Now I was in the mood for Sephiroth. I selected Platinum Match and started to fight him. Not once was I successfully hit by Sin Harvest (I was extremely lucky, a few times)! I dodged, blocked, and cured as necessary. Late into the battle, I noticed that his life bar was in the green, and one more string of hits would beat him. I didn't care what he was about to come at me with, I was going to hit him now. I lunged at him and gave it all I had. Suddenly I see a flash of light. The level-up message appears, and everything slows down. I sat in shock and awe, letting my heartbeat slow down, as Sephiroth stumbled back and disappeared into a flash of light. I had beaten him! I had won! I faded out of the arena and saved immediately.
Part 5 - Empty
Sephiroth stumbled back and disappeared into a flash of light. I had beaten him! I had won! A few minutes later, a thought came into my head. Now what? I had completed all of my goals: I had beaten the game (very long ago), I had attained the ultimate keyblade, and I had beaten the, proclaimed by all videogamers of whom I know, hardest enemy of the game. Now what?
Part 6 - An Answer
I have beaten every enemy in Kingdom Hearts, now...except for one. Yes, the only monster that has eluded my list of the beaten is the extra boss enemy in Agraba's (spelling?) desert. I don't have much of al will to beat it, though. I have yet to work up a successful strategy. I may feel a little empty, but I still hae some work to do. I need to find a few dalmations and trinities, grow to level 100, and obtain the Deep Dive movie (I may have even more than that). I am also waiting eagerly for KH2!
Did you actually read all of this?! If you did, I am impressed, and I thank you. I hope that this didn't bore you too much. I tried to make it dramatic, because that's how I feel about it, and I want you to be interrested.
Uh, good job in beating him so many times!
Now, try and beat him in Final Fantasy VII! I haven't beat Kingdom Hearts yet, due to my lack of PS2. 
. Very dramatic also. It kept my attention!! I too have beaten Sephiroth...(more times than I can count). Good job and you'll beat Kurt Zisa. He's easy as long as you use your items wisely 
.
It sounds really cool.
.
. What am I supposed to do now?
