Kero and Mokona is the 44th episode of Tsubasa: Reservoir Chronicle.


  • Everyone except Mokona shrinks.
  • The group meets the guardian deity, Kero.
  • Mokona and Keroberos retrieve the feather.
  • Mokona gets to cuddle with everyone.


The group arrives in a new world, but Mokona once again seems to be feeling down even though she says that she is energetic.

Mokona senses that there is indeed a feather in this world, but for now the groups decide to set up camp by a pillar depicting what Syaoran thinks is this country’s guardian deity. When dinner time comes, Mokona surprisingly doesn’t want to eat. Then at bedtime, she is unable to choose who to sleep with that night. Mokona mentions that she wants to snuggle up with everyone at once, but Fai says that she is just too small. Mokona eventually settles on Syaoran, but still ends up being unable to fall asleep.

Mokona contacts Yuuko even though she has nothing really to say – she just wanted to see Yuuko for a bit. Although Yuuko avoids directly answering when Mokona asks if she ever becomes lonely for no apparent reason, she does suggest that Mokona is homesick. Upon hearing what homesick means, Mokona doesn’t think that that’s it. Mokona tells Yuuko about the figure on the pillar, and Yuuko sets Mokona’s mind at ease because she thinks that this guardian deity will be able to figure out Mokona’s pain.

That night, as the group is sleeping, a bright light starts to emanate from the top of a nearby mountain peak. When they wake up the next morning, Kurogane, Fai, Sakura, and Syaoran are all tiny whereas Mokona retained normal size. Since they are so small, Syaoran and company almost get stepped on by Mokona, but are fortunately saved when Kero arrives and stops her.

Kero had earlier sensed that the long-awaited savior had arrived and had come out to find this person. The group returns to Kero-chan’s home inside a tree where Kero introduces himself as Keroberos, the guardian deity of this Kero Country. Fai remembers that they saw something very similar to the Kero balloon back in Piffle World. As for what happened with Syaoran and company, Kero explains that a feather fell down onto the nearby mountain, turning it into a magical mountain that makes humans tiny. He knew Mokona was coming through a dream and considers her to be the savior. Mokona and Kero-chan are the only ones big enough to go up the mountain, and so they leave Syaoran and company behind.

The two have to brave cliffs and blizzard conditions in their quest to get to the feather. At one point, Mokona has to even use one of his 108 Secret Skills – Super Suction Power – to protect them from a rockslide caused by a bolt of lightning.

Back at Kero’s home, Syaoran decides that he should go up after all, and Sakura volunteers to go with him, but Kurogane stops them both. Fai makes them realize what it means to be small and says that what they can do for now is to believe in Mokona and wait for her return. Syaoran now knows that waiting is painful, and so he apologizes to Sakura (since she’s always waiting).

Mokona and Kero-chan eventually do reach the feather, which seems to have a protective barrier around it. Kero blasts open a hole for Mokona, and Mokona sees that there’s actually a butterfly inside the barrier with the feather. She figures out that the butterfly must have wanted everyone to be the same size as it, which is what caused all the people to turn small. But with time running out before the hole closes, Mokona apologizes to the butterfly and takes the feather. She barely squeezes out before the hole closes.

Mokona and Kero return back to Kero-chan’s home, but Syaoran and company are still kind of small. Kero thinks that it’ll take some time for the magic mountain’s curse to go away, and Mokona gets an idea for the meantime.

That night, Mokona sleeps with Syaoran, Sakura, Fai, and Kurogane in Mokona’s arms; just like Mokona wished. Sakura wakes up the next morning after having a dream of a memory where she fell out of bed. She’s actually grown back to normal size and quickly realizes that she’s sitting on top of Mokona.

Since it is now time for the group to leave, Mokona and Kero-chan have to say their goodbyes to each other. Although having to separate from Kero is sad, Mokona is at least not feeling down anymore. They then notice that there’s a rabble of butterflies floating above them, and Sakura suggests that they’re all here to say goodbye to Mokona. As Mokona and the others are disappearing to the next world, Kero hopes to see Mokona again.
