Friends
dart feld
"Doesn't she have a better way to say goodbye?"
Meru thinks Dart is cool and decides to join him to get back Lynn since no one would take her seriously. She explains how to get into the Valley of Corrupted Gravity and pushes her way into the party. Meru believes interesting things will happen if she is with Dart and it turns out she was completely right.
Dart doesn't especially like the girl but doesn't hate or find her annoying either. He seems to acknowledge her when the others ignore her outbursts. Because of this, Meru hangs around him and Shana quite a bit.
shana
"Sorry. But we gotta get going."
Meru likes Shana a lot and likely hangs around her because of her kind disposition and young age. Shana also treats Meru equally instead of like a kid. Because of this, Meru is close to Shana and wanted to protect her when the ceiling began to fall at the City of Gigantos. Meru also takes care of Shana at the end of the game and cares for her greatly. Her main concern is of Shana, not the destruction of the world.
Meru also uses Dart and Shana's relationship to learn about her own with Guaraha. She has no idea how to act around him or how to form a relationship and by observing the two, Meru is able to understand her own peculiar engagement and decide how she wants to pursue it. By the end of the game, Meru is able to go back to Guaraha confident in their relationship whereas before she was constantly avoiding it.
rose
"We don't have time for playing with a kid."
Rose is hardly impressed by Meru's introduction and finds her to be an annoyance and is opposed to her joining the group but ends up having little choice in the matter. To her, Meru was just a kid that was in the way. Rose shows no interest in the girl following them and doesn't interact with her directly. She seem irritated that Meru thinks their journey is going to be fun.
In return, Meru finds Rose to be dark and scary at times. During the trip on the Queen Fury, Dart chastises her for saying bad things about her friends when she tells Dart she finds Rose to be weird and that she might be involved in shady things since Rose is never telling them about herself. Dart reminds her that Meru is pretty mysterious about her past as well. Meru and Rose have some things in common, more than Rose would likely admit.
Rose also agrees with Meru that the world cannot be destroyed because everyone is the same. Rose also claimed that it was the first time she had ever agreed with Meru. Meru questions if it is the first time they had ever agreed on something. Both have a strong streak of idealism, Meru having much of the idealism Rose used to follow.
haschel
"Right!? I am looking forward to it! I wonder what I can feast on there! "
Meru is often paired with Haschel during cutscenes as they both joke around a lot and act childish. They both sneak around the kitchen of the Twin Castle waiting for dinner as well as spy on Dart and Shana when they are reunited. Haschel likely sees his daughter Claire in Meru and enjoys being around her for that reason as well as for Meru herself.
When Haschel fakes being hurt in order to sneak off and confront Gerich, Meru stays behind to look after him. This throws a wench into his plans. Meru was concerned about her friend but also thinks it's Haschel's fault for over doing it. She's certainly not afraid to say he should have thought about his age.
albert
"I am traveling as your companion, and Lavitz's friend."
Meru has no problem treating Albert like she would anyone else. Albert tries to teach Meru little thinks such as when he reminded her if your brawn doesn't work, you should try your brain. Albert is able to relax and continue on the path he has chosen both to the strength of his friends as well as the charm and carefree attitude of Meru and Shana. At the same time, he finds her a handful.
During the Queen Fury trip, Albert wanted to make sure Meru wasn't just traveling with them for fun and that she was really serious about the fights to come. He is glad to know Meru truly thinks for can contribute something.
kongol
"You enemy no more. Here Holy place of Gigantos. Me survivor."
Meru and Kongol do not interact much and Kongol ignores Meru on the Queen Fury when he's having a tantrum. Meru does not find him imposing in the least and Kongol seems to put up with her attitude and personality. Meru decides to wait with Kongol since it would be lonely outside when he can't enter Emile's room.
Kongol notes that when Meru and Dart come to collect him on the Queen Fury, Dart looks like he's having a hard time babysitting.
miranda
"Why didn't you tell us?"
Miranda is miffed that Meru did not tell them she was a Wingly at the palace. However Meru explains that they would likely have not believed her and that they might even have considered her an enemy if she did. Miranda can likely understand this feeling of rejection, as it would be similar to her feeling of abandonment.
Meru gets upset when Miranda accuses of her running back to her forest to hide. Miranda is very blunt and likely meant no insult. Meru also likely realizes that is Miranda's way of motivating her. Meru is also confused when Miranda claims she was lonely and often came to Kashua Glacier. However Meru is quick to understand when Miranda explains she was abandoned by her birth mother and adopted by Queen Theresa. Meru can also understand this feeling of abandonment as it is similar to her own outcast status with her family and relatives in the Wingly Forest.
