I've been wondering who to give my friendship items to I know Shizuka and Yoshitsune are on the top of the list due to their abilities aside from the two of them who should i focus on? since modelkit and goldfish(if i can recall it correctly) are not effective to them?

The Wiki helps a lot with this but if you want some suggestions:
-Give Ibaraki goldfish until you get moon king.. maybe more later if you want more bottles.
-Give Miroku Model Kits until you get the magatama list you want (check here -from bargains) and no more if you can avoid it since you can't unlevel partners.
-Give Kaguya model kits until you get ornaments. Even better, heavenly shield @lvl 19 iirc... which is kinda far... fated contractor is probably enough.
-Susanoo... you'll practically get fed levels later so I wouldn't suggest prioritizing him.
-Amaterasu, level when you can... she gives good bonuses.
-Momotarou, I'd suggest focusing on him after Ibaraki

Personally I'd prioritise Momo over Iburaki, but I guess that depends on how useful you feel Ibaraki is. I rarely talk to her or even acknowledge her existence, whereas I rely on Momotarou to help me level up my skills faster and to then evolve them. I can't really judge anything else though, so I'll leave it there.

I'm really confused between ibaraki and momo since most people say momo didn't help them too much but if I can get momo high enough to extract worthless skill I will not gamble my other good skills in exchange for a skill card, on the other hand ibaraki is like a fail safe partner to me, when all else fails and then you will realize that you got a special wine to turn the tables . If I level them both non of them will be useful enough so I wanna focus on someone

Momo lets you evolve skills, especially ougi skills.
+Skill levelling speed, which helps a lot with extracting and carding weps. You'll eventually need to gamble skills if you want good skills on a wep -or a triple lungestep sword etc.

Okay so EXTRACTING SKILLS DOES NOT MEAN REMOVING THE SKILL BUT ONLY GETTING SKILL CARD, I tought I can actually remove worthless skill so I don't need to gamble T.T

I'm unsure about extracting. I've only done it once. Extracted Crag Thrust I from my Chidori. and like you say it didn't seem to disappear, but then when I used a Skill Card the new skill replaced the extracted one. EIther the skill has been removed but the icon remains, or else I'm just ridiculously lucky. Until someone says otherwise, I'm going to assume I was very lucky not to accidentally delete my Rank IV or Rank VII skill.

Not quite sure what you mean... so here's what happens (for regular skills, ie. non-ougi):
-Extraction reduces the skill level by a set amount, but doesn't affect rank.
-Extraction does not change what skills are on a weapon
-Extracted skill cards act in exactly the same way as regular skill cards. They overwrite a random skill (so I guess you were lucky? Putting a rank I card on a weapon with rank 4 and 7 skills -very strongly NOT recommended).

I was trying to take OFF the Rank I skill so that I could safely replace it with a Rank IV. Originally I'd assumed that Extraction would mean the skill would be removed, and there'd then be a blank skill slot to fill without risking my other skills. When I got lucky, I assumed that that was the case, but my mind suggested the possibility that there might have been a bug that prevented an empty slot from being shown. Evidentally this isn't the case. That kind of makes me wonder what good extraction is. Okay, so there are some Rank IV or V skills that are pretty rare, but they're not *that* rare, I can find alternatives that work well for me. The main appeal (in my eyes) was the possibility of an unwanted skill being removed from the weapon so that a skill you actually *do* want can be safely added. Without that it kind of seems that Extraction isn't *that* beneficial. It has *some* benefit, but not enough for me to go ape over.

Smithed Weapons: You'll need them if you ever want any weapons past 106 -unless you don't mind a grey staff (107 iirc) or the Aragami Magma Odachi (Hell version) and there's practically no chance that you'll get the skills you actually want unless all the skills you want happen to be on cards.

Extracted skills are particularly useful (in combination with skill evolution 5) with the 105 mags since they affect rank 5, but have also been useful for getting multiple invigs on a staff, triple lunge step, or triple anything, really/triple, before overwriting with a VII skill.

i.e. very useful IMO, since there aren't many skill slots.
