Well, a starting improvement suggestion would be to spell Cu Chulainn's name right (you spelled it Cu Chlainn). Another improvement might be having a spot for the + levels (unless that is limit break?).

As for Eidolons, you can probably treat them the same as Kamihime, just take out the accessory stuff. I think a majority of players will not have more than 1 copy of significant eidolons, so you don't need multiple lines for a certain one (and if they do need it, then they can just copy paste a line in between). You can also possibly split the Eidolons (and weapons too) into gacha and event/free categories, and exclude normal and rares (except for maybe rare release weapons).
