Let's use Light monsters from the beginning
Here is a list of Light-attribute monsters that are easy to get and available from the early stage of the game. Build a deck that contains those monsters and summon them as much as you can even in the initial phase. See also the following 2 tricks:
Do not set, flip summon, or special summon them. It is said that only normal summon is applicable although that is unconfirmed.
If your Monster Zone is full with LIGHT monsters, conduct tribute summon. Or switch their battle position to defense, then standard duelists will attack your monster that have low DEF, and you can summon the next one.
Set LP Boost skills to your deck and use cards that regenerate your Life Points to complete one of Ishizu unlock missions, win a Duel against Ishizu with at least 6000 LP remaining. Joey, Tea, and Mai can acquire LP Boost skills by leveling up, and other also can acquire them as drop (duel reward) skill.
[LP Boost α] Increases starting Life Points by 1000.
Just unlocked her recently. maybe you think you have summoned that much, but really isnt. You have enough light monsters in deck? I use Yugi with power of dark and Rogue Dolls (Pegasus), Element Magicians, and The Stern Mystic - these monsters are spellcasters and are from light element, didnt take me long to unlock her by using them.
Ive been using a light only deck for about 2 months and her mission still hasnt came up

i already play all-light monster deck for 4 days until now and i play againts lvl 10 legendary duelist , and there is still no isuzu appear . can someone tell me why this happen and what i must do now ? i'm currently at stage 38 and cant proceed to next stage because of this quest
I've been farming with Cerberus so much you think I would have unlocked her mission by now, but I've made a deck with light monster to try and unlock her but I can't even find where I can see if I'm close to 200 or not
I use Yami Yugi with a couple of light monsters and I manage to unlock her. I have Rogue Dolls (Pegasus), Element Magicians, and The Stern Mystic - these monsters are spellcasters and are from light element, didnt take me long to unlock her by playing this style

I use a light deck it didn't work so how u trigger ishizu
Nope. I've been spamming a 20 LIGHT monster deck with tribute summons against LV 10 Gate duel legends for the last 3 days to no avail. Really hoping they fix it soon. :(
Update: she just unlocked for me after I sent a message to the powers that be, so I don't know if they did it for me manually or if something changed. Best of luck!

I unlocked her today in pvp ranked match. I was trying to unlock another chatacter at the time
Started new at 12am and summoned over 400 light atribute monsters until 3am then realized ishizu should have triggered but she didn'the. So now I'm posting the deck i used so someone can tell me what I'm doing wrong.
Unlocked her in 1 Day. Started a new game and summoned 1 Light Monster vs npc (gues it was "Element Magican") 200 Times. I made some screenshots (Ger) for you since i got pretty frustrated to unlock her in my frist try, too:
