Lord el-melloi ii (ロード・エルメロイⅡ世) - Fate/Series

I recommend you to set the lora weights to '1~1.2'

You have better to use quality tags including "masterpiece, best quality, amazing quality, sensitive, very aesthetic, highres, absurdres, newset, official art, anime screencap"

If you want a different outfit, put the default prompt outfit in the 'negative prompt'
