Stella and Diether met many sword practitioners who uses wooden swords to practice their sword art and on rare occasions, they are even using it in real battles.
However, the shinai that has a white leather strap in the middle and cap on its end was completely different! It was also made of a unique type of bamboo that it's hard to make a mistake recognizing such sword…
The two are also extremely familiar with this since they've held Reiji for a very long time.
Diether could still remember his master's weird instructions telling him not to unhand the sword for even a second. Because of that, he would just normally stare at the sword aside from practicing Kendo…
'Master Reiji… Is that you? Can you hear me?' Diether attempted to use their 'Sense Link'.
