wish that Kaku join in Marine and having similar role as Vergo

the devil fruit is for Nami or Carina?if giving for Nami, I think that Awa Awa no Ni is the best choice.It'll grant nami ability to control soap and bubbles. And with Nami's understanding, she will develop a new model of weather art that different from the canon.Of course it'll different from climate tact because that weapon can produce three type of bubbles (heat, cool and electrical). And for fruit's case, I think it only possible to make hot and cold bubbles.

suggest, it'll become two chapter. 1. Sibling's Tragedy (Elfman x Mirajane) plot: Elfman blame himself because he's the reason that Lisanna is dead, so Mira will support Elfman and make him to move on by offering her body. 2. Sibling's Reunion. (Elfman x Mirajene & Lisanna) Lisanna is come back from Edolas and the siblings drinks together and so accident will be happen.

if the male is Mad Treasure.It can make another story, females is Nami & Carina

invite Nami too. And if the plot is connected with movie, you can also take Carina in this stage.Turning point is Jaegar Family as bounty hunter get a war against Treasure Pirates and eventually save them.

next up?

how about make Saber to become Gilgamesh's servant. [this is can become a short series] After Gil become a real person because of holy grail, he will search Avalon. So, Shirou will die. Arthuria is still remember about 4th war and hated Gil. So he will dominate and force her to become his woman. they'll win war but Saber will become Alter corrupted by Angra Mianyu before it. Gil will use grail to summon Saber again and possess both of Saber and Alter.

One Piece, Shokugeki no Souma and Date A Live too please

it's good story especially if it keep be short series like this.but, I have suggest. How about make a little change:-like make the story with Saji as main with Sona and her peerages. -Vali chaos bridg's female member, you can change Arthur with Artoria [fate series].-Tobio from slash sog series.-Riser's view point, killing issei in his wedding and slaving Rias and her peerages. For Riser's story can include his sister (ravel) and his own peerages.-etc.

not really.I think it's more better to make many one-shots or short stories (like 3-6 chapters for evey series).because this plot not really connected and having plot holes.

next up?

how about make series that Shinji as mMain Character, Story plot:1. Taking Sakura's virgin and enslave her since 3 years before canon.2. After Sakura summon Rider, he want to taste heroic spirit (Rider).3. Playing with Sakura and Rider4. Rin knows about what happen with her sister, she'll make a deal with Shinji.5. Shinji playing with Sakura and Rin.6. Saber is making contract with Rin in that time (like UBW) and Shinji'll steal Saber's command seal from Rin.7. Playing with his servants (Saber and Rider)8. Crazy party with all of them.

domain battle between Gojo and Sukuna (ch 226).Tsukumo vs Kenjaku (ch206).

because Naruto is already fast and don't he need learn about it.aldo, FTG is not suitable for someone who always use kage bunshin.let's image, Naruto create many clones. What will happen is 2 or more think to teleport in same point, instead be faster, it'll distrupt his movement especially every clones can think independentely.to use FTG, he also need to think the environment and prepare coordinate too. After teleport, it can make himself confuse if he is not planning 2-3 move ahead the enemy because his angle will be drasticly change.

simple domain also can do it.

yesand maybe make Yuji to awake Itadori Kaori's cursed technique (Antigravity System) after he eat Sukuna's finger.make Yuji's existence as vassel is be force by binding vow because of kenjaku's plan. That's way Yuji get extraordinary power but not stong as Toji. And the vow will be broken when he gain curse energy from Sukuna's finger.

wait, how about Long Yuyin instead. Or maybe Gu Lan.

wish he will get adamantine chain. Set him to use Kurapika [HxH] as example.
