Tetsuo has offered to work with the girls to figure out how Hikari and Yuki, who don't handle heat or sunlight well, can spend summer in comfort.

When it comes to effort, I don't 
want to place second to you.
،عندما يتعلّق الأمر بالمجهود
.فلا يوجد من يجاريك في ذلك
Ich werde mich auch
so wie du ins Zeug legen, …
¡No dejaré que me superes en esfuerzo,
¡No quiero quedar en segundo lugar,
L’énergie que vous nous insufflez
nous donne des ailes !
Non voglio essere di meno e farmi battere da te!
Não quero ficar atrás do 
senhor no quesito empenho!
И я не хочу уступать вам в старании,
