Kaito Aiba

About
He is the customizable protagonist of the first Pastel Chime game. You can change his first name and his class.

He coasted through most of his life, never putting in much effort. This changes drastically in the beginnings of his 3rd year at the academy where he fails to protect his classmate and childhood friend Meusel Clasmine and is confronted about it by Lloyd Grants. He decides to see it as a wake-up call and asks Meusel to help him train to make up for the 2 years he lost to lazing and hopefully still graduate.

He is generally laid back, but takes dungeoneering seriously after what happened. He's a pretty regular guy in class with his only standout relationships being the constant fighting and making up with Colette Blause and his rivalry with Lloyd. Otherwise he seems genuinely friendly, going out in the pouring rain to help (and become friends with) Kaina Shikido and Setsuna Shikido despite never meeting.

He moved next door to Meusel in the town of Naru around 10 years prior to the events of the game. Before this he used to live in the royal city Dios.

He actually met Colette before, but initially doesn't remember it. She is the same half-elf child he played with in Dios before moving away. They didn't get a proper chance to say goodbye as the final days he wanted to tell it on had bad weather so they didn't play. He had a crush on this younger Colette.

His various endings differ: In Meusel's end he ends up saving her from being consumed by the Demon Lord after beating both Kaina and Setsuna. He did so by using and old notepad from their childhood to remind Meusel of who she is. After this the dungeon starts to collapse, but Kaito remembers the return spell he got from Bennet Koujour and they escape. They fear that the time seal cast on the dungeon had a strong effect and they actually spent hundreds of years there. Colette shows up (now an adult) and informs them of it being 10 years. Bennet got called up to graduate them and as they leave the seemingly deserted building, loads of people line the road to congratulate them.

Colette's end sees him save both Meusel and Lloyd with the help of a now adult Colette. She casts a return spell as Lloyd's was broken but are attacked by a demon lord controlled Kaina. They hold him off long enough for Meusel and Lloyd to make it out, but they are stuck with diminishing air. While stuck there he mentions knowing it is Colette and they have a moment before passing out. When they return, they are both in the infirmary but despite now really being lovers, they bicker just as much as usual.

Celles's ending has them take the exam together which makes them narrowly miss out on a hostage situation caused by Kaina and Setsuna using spatial magic in the dungeon to find the soul vessel. Him and Celles go after them as he wants to know what they are up to. They run into Setsuna which they beat, but he gets tired out. Celles continues onwards by herself for him and her "friends". She confronts a reluctant Kaina who uses her bullies lives to test if she really cares and allows himself to be killed by her if she so tries as he is seemingly moved by her feelings. She does so and afterwards they both graduate. She becomes a teacher and ends up marrying Kaito.

Saya's end has him go down the dungeon to stop Kaina and Setsuna after Meusel got kidnapped. Saya snapped at the idea out of jealousy and got slapped and left to think on her behaviour. She later comes down to save him from a pitfall and they go on. They fight and beat Kaina and Setsuna in the depths and save Meusel. The door is locked, but they have a return spell. Just as they use it, a horde of monsters attacks. Saya pushes Kaito in the spell and holds them off. He immediately decides to start rescue efforts and he arrives 30 hours later. He initially thinks her dead, but she weakly manages a response. 5 years later, they are adventuring around the world hoping to find great treasures (jokingly to convince her dad).

The Chisato route has a normal graduation dungeon run and ceremony, but before Kaito can get to the ceremony he gets KO'd. Chisato, on Kaito's advice, decided to very aggressively pursue their love much to Kaito's dismay. It is revealed that she is a girl however, which leaves him further confused. 2 years after this unreported crime, she is dating Kaito and is acting and dressing more girly as with Kaito she doesn't need to worry about taking over the dojo herself.

Abilities
He can work hard if he has to and this is reflected in his abilities as an adventurer which vary depending on what the player chooses. He can be a great mage, diviner (priest), warrior or scout. He can mix and match into various half-classes.
