Vinete's Mu no Kamae would put her in any position she wanted if they are in a team battle. This is what Reiji thought about her abilities.
Apparently, Reiji wanted to somehow create a proper team battle of sword practitioners someday. After all, team fights have a lot of benefits in learning the art of swords compared to individual training in the Dojo.
Team battles will allow them to properly gauge their opponents, find their weaknesses, and learn to exploit their advantages. They will also have a team spirit which is even more important when roaming this dangerous world.
There will be many benefits in this aside from that and Reiji is very aware of that.
This is why he already started thinking of introducing this team fight to them.
'I guess I can consider their best positions after this battle.' Reiji thought.
