Nashi
Nashi is an orphaned Nezumi adopted by the planeswalker Tamiyo after his village was destroyed.
History
The planeswalker Tezzeret set fire to a nezumi village. Nashi's parents died in the process and he was left heavily scarred due to fire elementals sent by Baltrice. The ratfolk inevitably killed Tezzeret, making the youth watch.
He was subsequently sent to various houses which he refused as he felt his foster parents were trying to replace his dead parents. This changed when Tamyio came to him and insisted he called her nothing but Tamiyo.
Though loving his new family, he often felt the runt and was frustrated due to not being able to fly like his Soratami siblings.
When Ajani came to their house, Nashi was initially distrustful, but came to sympathise with the planeswalker and his loss of Elspeth Tirel.[1]
Neon Dynasty
Tracking Tezzret, Kaito Shizuki inevitably tries to track Nashi for information. Tamiyo intercepts him and appeals to leave him be due to his trauma. In his brief apparence, Nashi is revealed to be interested in technology and is excited about Kaito's drone, before asking Tamiyo if he can go to the market to get a new data chip.[2]
