I think you're really missing out on the Plum Blossom Onigiri that you can make with Kaguya (presumably with Subaru as well if you're playing as Kaguya). Level 1 grants 1300 HP, 200 RP, and Auto-Heal Spirit +0.5%. So burst of healing for HP & RP and then a passive regen for your RP. Best of all, it's a variant of the Onigiri recipe, so it only takes 1 Steamed Rice. Super easy to make. The only caveat is you have to make it at an izakaya to use the Cook Together feature.
