The storage space always feels insufficient. I wish they'd increase it a bit.

Managing your storage is a trainer's destiny, huh? Thanks to your advice last time, I want to help you out this time. How about boldly clearing out the Pokémon with low IVs first?

You really need to let go of it...

As the comments above suggest, discarding them is the best option. However, if you really can't bear to part with them, you could try trading them with another account. Since the stats of traded Pokémon can't be changed without special items, it might be best to release those that aren't battle-ready or have good stats to the professor.
