Jean
A random commoner from the Republic (The guardian tree arc's setting). Leon found Jean when he took a part-time job at a family restaurant. (This is because Mary was angry at the five idiots only spending money yells at them to make money!). Jean is aware that Leon is a noble and tries very hard to make sure that Leon doesn't get pissed off (since most nobles of the Republic have already shown had crazy it gets). He was once a student in the Republic's Academy but had to drop out because his financial situation was becoming dire. Leon, however decides to personally fund Jean so that he may get an education and help further any plots Leon will have in the Republic's future. More memorably, Jean is the owner of Noel, the dog.
Noel, the dog
Noel, the dog was originally in a very pitiful situation. On a whim (no not a calculated plan to milk more money) Leon decided to save dog!Noel and take care of her. However, Luxon informed Leon that even if he invested resources to heal dog!Noel it will still not survive past a week. Leon decided that he will take care of dog!Noel anyway and treats her the best he can (yes, he was not being a P.O.S. this time). For instance, to make sure that dog!Noel would feel relaxed in the last few days Leon purposefully purchased
a baby's crib, the best dog food, and spend as much time as he can with it. This is while the five idiots just had to force Leon to hand over his (recognized to be the treasure from the dungeon) ship named, Partner. After being saved by Leon, it had a peaceful life for the last days of its life and was fond of Leon. It even died peacefully, and Leon decided to burn dog!Noel’s body into ashes and keep it in a jar. When Jean heard what happened to Noel, the dog, he was grateful that it didn't spend what little time it had hating Jean and living as happily as it can. Jean was also given the jar containing dog!Noel’s ashes.
Noel, the priestess
The heroine of the sequel galge. She was originally in an abusive relationship with Erik because her twin sister (with a bigger bust) urged her to do so. Noel followed what her sister said because her parents pretty much ordered her to follow what her twin says due to the parents putting all their hopes of removing the tree's protection from Republic's nobility into the twin (the twin was furthering these goals accidentally). She was freed from said relationship when Leon decided to intervene. Eventually became the priestess of Leon's sapling instead. Has feelings for Leon and is shy but not against being in a romantic relationship with Leon. Conveniently has the same name as the dog and Olivia and Angie assumed Leon was not taking care of dog!Noel (sheltering it, feeding it, keeping it relaxed), but taking care of human!Noel (implied mistress). Has a buff male servant who acts like an okama and is a part of the Republic Academy’s teaching staff.
Kyle's mother
Female elf. Can't remember her name. Has a magic that accelerates the growth of plants. May also be able to speak with plants as well (I'm assuming here). Hired as a servant of Leon's parents’ house. I think she has big breasts, but I may be wrong.
