Why does Sakura not have a personal summoning animal?

[Nebula]

Chapter 538 sakura summons a slug named kirihime.

 

[Ōkami]

Katsuyu is slug. All slug are Katsuyu.

This is life.

A beautiful post.

Kishi's too lazy to think of one

its rather she is too much of a fodder to get one

 

[Flawž]

Maybe because kishi plans on killing Tsunade making katsuya sakura's.

 

[Kazehime Seirin]

Because she's Tsunade No. 2<3

 

[Tobi98]

Because Katsuyu is probably the only slug summon

 

[Your Creepy Stalker]

All the slugs are just clones of Katsuyu.

B****es don't have personal summoning(s) !

 

[FemmeFatale]

It was a clever pun on cellar mitosis.

 

[Wabbit]

Katsuyu is Madara of slugs.That slug is Katusya This slug is Katsuya and all slugs are Katsuya

 

[Zol]

Wasn't this explained? Katsuyu is the only slug, but she is far larger than any other summon, so when a slug contract summoner calls her, only a small part of her actually appears. She is one of a kind.
