Isekai Yururi Kikou: Kosodateshinagara Boukensha Shimasu

Two isekai fantasies with smol kid MCs and fluffy animals. Their stories differ where Mofunade's MC is royalty whereas Iseyuru's MC are normal folks but there are equal parts cuteness and fun in both. Main difference is that the person who isekai'd in Mofunade turns into the child whereas Iseyuru has the person isekai'd into an adult but looks after two children. In turn, Mofunade's child is very independent with her past knowledge whereas childcare is a main theme in Iseyuru as the children still have the mind of children. Mofunade does get serious along the way in comparison but this is subject to change depending on how Iseyuru pans out. read more 

Isekai anime revolving around kids exploring a world which kinda wants to kill them. The setting and situations of the protagonists in these two anime are rather different, but these two are practically as cute as each other. 

Adventurer finds kid(s) in the woods and takes care of them while going on adventures. Super cute and wholesome moments.  

Both are light-hearted fantasy isekai anime with an overpowered male protagonist ML become an "older brother"figure and recruits children into his party  

Two isekai's with an MC that becomes an adventurer going on adventures accompanied by beings from the isekai-world. They both have talking animals in them but main difference is that Iseyuru has the MC look after two children as well. One of the main similarities is that they bring recipes/food knowledge from Earth to the isekai whilst both shows maintain a healthy balance of action adventure sequences and light-hearted fun. Tonsuki is also a gourmet anime and heavily relies on this aspect whereas Iseyuru uses food every now and then but see characters enjoy digging in to good food. If you like a fun relaxing time that makes you happy in one, you'll also enjoy the other one. read more 

Two fantasy slice of life isekai's that are equally light-hearted and have enough action sequences to make it exciting with the plot of the character's journeys. In both, the MC's are reincarnated for different reasons but would regularly converse with the God's of their universes and are blessed by them too. The MC's in both are always meeting new friendly people along the way. Main difference is that Kamihiro features lots slimes who are tamed by the MC whereas in Iseyuru the MC is accompanied by two children, plus the MC in Kamihiro reincarnates as a child but the MC in Iseyuru is still himself.
